Thank you for your video.Sir I have a doubt for ordinary hazard 1 the density is .15gpm/ft2 and that is for 1500 ft2 but if I get a room which is more than 1500 ft2 suppose its 1700ft2 then what will be density?How can i calculate the density in that case.Sorry for my ignorance
Suggest to review graph of density and protection area of sprinklers then you will understand. Density will change according to area
@@TanweerAhmed Hi sir, which type of sprinkler connection is used for warehouse ( for rubber related industry) ?
Watch my video "Classification of occupancy" according to fire hazard then fire fighting decided. However, in your case, class A foam fire extinguisher or system used
@@TanweerAhmed what will be the usgae of extended coverage sprinkler system? Is it can be considered on the warehouse area?

Sir kia yehi sb calculations extra hazard group k liye b use kr saktain hain same to same
Yes but pipe size calculation required. No pipe schedule method will be used in extra hazard
Thanks
Welcome
Please refer worked out calculations / formula used in HASS Software to find pressure in pipe ( Tree type sprinkler and Deluge water spray for transformer ) . Already i succeeded to find out pressure loss using Hazen william ,But still i need to find pressure in pipe - same elevation and in different elevation
Ok noted
Very useful video , thanks for the information . I have a question . suppose I want to design firefighting sprinkler for a school laboratory it comes under which hazard ? light or ordinary or extra ? in the new NFPA it does not state it comes in which hazard . How do i find this ? Thanks
Watch may video, fire hazard occupancy
sir extra hazard grp k b isi trha lgaty hain kia?
Yes
sir. could you please make one video on fire supperession Kitchen sysetem?

Sir fire NOC pr bhi video bnaye
NOC?
Assalamu alaikum tanveer bhi I want to know as per NFPA requirements what will be the minimum area that sprinkler is needed in the building.
If you want to fire protection on automatically then single story or double story house or any type buildings fire sprinklers are required
Sir please guide what type of fire fighting system can be installed in a sulphur godown.. It is powder form and its qty. is 250ton.. Please help..
The burning sulphur surface should not be disturbed by use of high pressure jets of water or other extinguishing medium. Use fine sprays of water or snuffing steam or extinguishing foams such as carbon dioxide. Use of halogen based fire extinguishers is not recommended.
PLEASE MAKE A VIDEO ABOUT WINDOW SENSOR SECURITY SYSTEMS
Ok noted
Sir, really great video, simply superb,
I have one doubt, NFPA 13states 52'000 sqft for any one one floor for a sprinkler riser, so can i connect 3 floors of 50'000 sqft on one riser or maximum 52'000 sqft combined only to be connected
From my knowledge which I have understood from NFPA wordings that only one floor 52,000 sq.ft for only one floor. I think yes, you can connect
@@TanweerAhmed yes, and here in india maximum 1000 sprinkler /gong valave, so to avoid any objection from fire authority we limit tye connection up to 1000 sprinkler
I have no knowledge about Indian standard. If there is change then you should follow as per your country standard because they are final authority of approval and decision making.
Can you please explain drencher system calcultion and there drencher size
I have no experience
Light and ordinary hazard m sprinkler line test pressure kitna hota h please btay
Pressure shall not more than fire sprinkler rating for both cases
Could let us know
no of sprinkler risers in building having height more than 120 m
Standby sprinkler riser required or not as per nfpa 13
Refer NFPA 14 standpipes (Risers) detail
🙏Aapane 1500 ko devide karne ke liye 130 ft kahase liya,
Hum log meter me karte hai isliye thoda confusion hai.pls bataye
Number one point is 130sq.ft, again check in video then will understand
Ok....thanks
Nice
Thanks
Is it must 3 sprinkler in a branch ? As per NFPA calc. no. of sprinkler in branch is 5, If only 3 sprinklers placed then its correct or not sir?
According to hazards then number of sprinklers change in branches but follow NFPA calculation
Sir could you please make abedio on , which building which type of system shout be installed
Okay
@@TanweerAhmed jazakallah khair sir
Sir can you design Petroleum storage tank (vertical tank) fire fightingsystem
What do you want?
Sir I have question about the pipe schedule method, what if the number of sprinkle is more than 275, which means 6" pipe can not be used and what is the maximum sprinkler for 8''? and the second question is instead of using pipe schedule method, how to determine number of sprinkle and pipe size using hydraulically method? thankyou Sir.
Pipe size calculation is right method for actual pipe sizing according to flow, pressure, velocity, friction losses of pipe, fittings & accessories, etc....However, different methods are used for pipe sizing best is hydraulic calculation...use Elite software or anyone else for this purpose
@@TanweerAhmed Thank you Sir for the answer. Could you please add English subtitle on your Elite Software Tutorial?
Which software is best for hydraulic calculation? Sir
Elite software
If floor plate is of 8000 sqft then we have to take area of protection 8000 or 1500?
If same same fire hazard then take 1500 and if different hazard then add hazards.
Hy sir ...
Koi fire fighting ka project hoga toa btaiye ga

Assalamualaikum Eng Tanveer Ahmed. I have a question. If I have multiple rooms, how spacing is calculated? Should I consider the 1500sq.ft as standard there as well? If possible make a video with multiple rooms. Thanks.
W.Salam, If you have same hazard and multiple rooms then also you have to consider same 1500sqft design area
@@TanweerAhmed for example I have multiple rooms with area of 300,500,800 and 900 sq.ft. can you help me to understand how I should consider spacing in these areas. If possible I'll share project details as well for reference.
Sorry for the inconvenience
Assalamualaikum Eng tanveer ahmed. Can you please provide information about the above comment.
I have already informed, watch my videos and practice accordingly
sir plz riser k bary main b kuch btain
What do you want to know about riser?
@@TanweerAhmed sir riser hoty kia hain ham in ko kitny area pay lgaty hain maximum are kitna ho ga jis main riser lgain or q lgaty hain riser sir please mjhy achy say bta dain main sirf aap hi ki videos dekhti hoon and i am also pakistani....
What is the min and max residual pressure at the remotest sprinkler as per nfpa 13 ?
According to NFPA 13 the remotest sprinkler depend on the occupancy hazard classification and the sprinkler type.
For Light Hazard Occupancies (e.g., offices, schools, retail stores), the minimum residual pressure at the remotest sprinkler is typically 7 psi (0.48 bar), and the maximum residual pressure is 20 psi (1.38 bar).
For Ordinary Hazard Occupancies (e.g., warehouses, manufacturing facilities), the minimum residual pressure at the remotest sprinkler is typically 10 psi (0.69 bar), and the maximum residual pressure is 25 psi (1.72 bar).
For Extra Hazard Occupancies (e.g., power plants, chemical storage), the minimum residual pressure at the remotest sprinkler is typically 20 psi (1.38 bar), and the maximum residual pressure is 50 psi (3.45 bar).
@@TanweerAhmed thank you very much
Sir aap kaha rahte hai, Kya aap hame Sprinkler system sikha sakte hai,
I live in Sindh, Pakistan 🇵🇰
Watch my videos for sprinkler system
does floor size of building play into the calculation? Thanks
Remote area calculation is given in NFPA standard which is minimum flow requirements of flow for sprinkler system from design point of view, therefore this calculation is required which have been explained in video
@@TanweerAhmed my point of confusion was that no matter how big the building is, as long as the hazard category is ordinary hazard, you will end up with the same size design area and density , and because of that, you will end up with the same results for water demand and pressure.
@@yadali4833 Here are some conditions: 1. System protection area limitations (one floor maximum should not greater this limit then use remote area density graph and calculate flow)
2. If system protection area limitations cross the limit then another riser added and also additional remote area density procedure adopted and to be added
3. Residual pressure is given in NFPA 13 but we have to calculate pump head pressure.
4. For head calculation used hydraulic calculation procedure. Examples also given NFPA 13 standard and also my video available for guidance.
5. If you have any questions, welcome😊
6. Reply is based on my knowledge but I may be wrong. Kindly highlight my mistake if you found...‼️
Please can you make a video explaining in English 🙏🙏
Subtitles in English is available
sir, if we use extended coverage sprinkler .can we use pipe schedule table to size the pipe ??
Yes can use because NFPA-13 allowed pipe schedule method as per hazard occupancies. I have used in this video
@@TanweerAhmed received, thank you sir.
Welcome
For extended coverage there is a separate table for sprinkler spacing. The pipe schedule will remain same as engr. Tanveer replied you. Extended coverage spacing and height factor must be considered. Max coverage height is 6.1 meter.
Kya fire me stenar lagta hai aour lagta hai to kaha lagta hai
NFPA recommend that if water is clean then no need for strainer and if water is dirty then provide strainer.
Conditions:
1. If water is clean then you should provide strainer in makeup (inlet) pipeline of tank.
2. If water is dirty then provide strainer in suction of fire pump
difference between automatic balancing valve vs picv
Watch my videos
for multi basement car parking of area 70*30m how will be the remote area ?
can any one show me some example
I have explained remote area in various videos
Sir suppose I have a floor area of 10,000 Sq ft.
Then to find number of sprinkler ,I have divide floor area with 130 Sq.ft .
Am I correct??
Please correct me if am wrong.
May be number of Sprinklers but 130sq.ft is not fixed value for single sprinkler. It change according to hazards types and it's condition
sir, how can we change sprinkler in running pressor.
Watch my video testing of fire sprinkler system. I have explained the procedure of sprinkler replacement
sir one of my customer is running the Overhead Fire Pump 24 hours.
now Safety Relief Valve is Leaking !
Safety Relief Valve (the three hole flange disc ) leak has been repaired by trained
Plumber/fitter.
But should we run Fire Pump at all times ?
I don't Think so !
NFPA 25-1998 did require the annual fire pump flow-test for both electric-motor driven fire pumps and engine-driven fire pumps to have a 30-minute churn test at no-flow conditions to begin the test. This was to ensure the pressure relief valve opened to allow circulating water to cool the pump when operating at standby (i.e. no-flow) conditions.
But Sir actual length and width of Room is different. Like as 50*30 feet square. Then how to define length and width.
There is no much difference. You can consider both options if you have any confusion
There is no much difference. You can consider both options if you have any confusion
@@TanweerAhmed Sir
My opinion sprinkle distance from wall (1 to 4) feet. According to site conditions.
The minimum sprinkler acceptable pressure = 7 psi (NFPA13, paragraph 27.2.4.11.1)
27.2.4.11 Minimum Operating Pressure.
27.2.4.11.1 Minimum operating pressure of any sprinkler shall
be 7 psi (0.5 bar).
27.2.4.11.2 Where a higher minimum operating pressure for
the desired application is specified in the listing of the sprinkler, this higher pressure shall be required.
Table 19.3.2.1 Water Supply Requirements for Pipe Schedule
Sprinkler Systems
Occupancy classification ordinary hazard minimum residual pressure required 20psi
@@TanweerAhmed As per NFPA 13, 8.6.4.1.4.4 Sprinklers installed where the dimension perpendicular to the slope exceeds 8 ft (2.4 m) shall have a minimum
pressure of 20 psi (1.4 bar).8.6.4.1.4.4 Sprinklers installed where the dimension perpendicular to the slope exceeds 8 ft (2.4 m) shall have a minimum
pressure of 20 psi (1.4 bar). Sir, we not found ordinary hazard minimum residual pressure required 20psi. Kindly help to clear doubt.
Do oil and gas facilities come under ordinary hazard group-1?
Watch my video about hazards
Sir sprinkler ka pressure test aur leakage kaise test karte hai..
Sprinkler these technical data checked and witnessed by the manufacturer of sprinkler. We check the pipelines and fire pumps pressure test as per NFPA requirements.
@@TanweerAhmed sir abhi fire pump nahi laga hail hospital building ke tank ka kaam chalu hai. Koi external pump use kar sakte hai kya
Yes
Sirji, can you please do a video on estimation of fire sprinkler system ?
Elaborate the estimation. What do you want in estimate?
@@TanweerAhmed For example in a GTG area, the number of sprinklers required, linear feet of pipe, fittings etc and the manhours (labour hours) to install it.
It can be calculate from drawings and contract documents. Insha'Allah will try
@@TanweerAhmed Looking forward to it sirji. Inshallah 🙏
Sir how I make automatic fire detection system
Get help from designer
Sir,
If residual pressure of sprinkler is less than 20 psi then for increasing pressure we have to increase the head of pump. Am I correct
This pressure is for design purpose
@@TanweerAhmed means residual design pressure should not be more than 20 psi. And what is the minimum residual pressure.
It is minimum
