Dear Engr, Can please tell what do you mean by min and max pressure for 3 way Fire hydrant, Is it residual pressure( Min) and Static pressure ( Max). please reply
Thanks for sharing.. If there are 6 hydrants & consider a worst situation in which all of the hydrants need to be used, even in this case should we select a pump with 250 gpm & 175 psi(adding the frictional losses)???
@@TanweerAhmed thank u sir for ur response.. u have mentioned in video that flow required by hydrant is 250 gpm. Is this requirement only for 1 Hydrant or would be enough for all hydrants in working condition?
@@MuhammadJawad-mx3yh Not like this, NFPA recommended taking two most remote hydrants to hose connections &further hydraulic calculation and then finalized pump flow, pressure etc.

السلام علیکم تنویر صاحب سر میں نے آپ کو بتایا تھا کے واٹر مسٹ کی ویڈیو اپلوڈ کریں جو ابھی تک آپ نے کی نہیں ہے مجھے امید ہے آپ جلدی اپلوڈ کریں گے اور واٹر مسٹ کی ویڈیو جو اپ لوڈ کریں گے واٹر مسٹ کا پورا سسٹم کے بارے میں آپ بتائیں
وعلیکم سلام بائی صاحب، واٹر مسٹ سسٹم پر ویڈیو انشاللہ اپلوڈ کروں گا، مگر یہ سسٹم نہ میں نے لگایا ہے اور نہ اسکی پڑھائی کی ہے، اس وجہ سے کچھ دیر ہوگئی۔ انشاللہ جلد اس پر کام شروع کروں گا۔ دیر کے لیئے معذرت۔
Eng. Tanveer u mentioned at the beginning flow at 20 psi, But in the last u mentioned 100 psi minimum pressure requirement. NFPA 24 doesn't mention about a 100 psi requirement as per my understanding . Highly appreciate if u can clear this thing to me .
Kahi par hydrant par AA, A, B, C Likha hota hay ya drawing may ya documentary par Likha hota hay.... Iska matlab flow oar color code pata chal jay ga Jo video may bataya hay
@@TanweerAhmed Sir, I always see your HVAC & Fire related video for better understanding. Now, I need specific reference of minimum & Maximum pressure for Pillar Hydrant. I appreciate your answer.
Very informative videos sir thank you
Welcome
Any idea about cost estimation and manpower evaluation for installing fighting systems in I mechanical industrial sectors
No idea
Thanks for sharing details about hydrants 👍
Welcome
@@TanweerAhmed what is the discharge pressure of any hydrant?? 6 Bar is it correct??
I have explained in this video i.e. minimum pressure 6.9bar (100psi) and maximum 12.1bar (175psi)
@@TanweerAhmed shukriya...
Sir jo hydrant above ground hote hai un sbko pillar khte he na ? Me isme confuse ho rha hu please answer dijie
No, Pillar is one type. Watch my other videos on hydrant types
@@TanweerAhmed jo two way hydrant rhta hai usike khte he kyaa
Yes two way 2.5" connections
Good work keep it up.
Thank you ❤️
Dear Engr,
Can please tell what do you mean by min and max pressure for 3 way Fire hydrant, Is it residual pressure( Min) and Static pressure ( Max). please reply
Working or residual pressure should be in between min and max pressure range
Excellent
Thanks
Tanweer habibi ,
On sme pillar hydrant written "250 w"
What is that ?
I think that 250W means 250gpm water flow rate
@@TanweerAhmed
May be it is "pressure washer" .
thank u sirji 4 NFPA details.
Welcome

Flow depend on the pump capacity and in worst case any hydrant can be used. Friction losses included in pump capacity.
@@TanweerAhmed thank u sir for ur response..
u have mentioned in video that flow required by hydrant is 250 gpm. Is this requirement only for 1 Hydrant or would be enough for all hydrants in working condition?
One number 2.5" size hose connection's maximum flow limit is 250gpm
@@TanweerAhmed means if there are 6 hydrants in working condition then 6x250=1500 gpm(taking 1200 gpm a/c to NFPA) 1200 GPM pump need to be select?
@@MuhammadJawad-mx3yh Not like this, NFPA recommended taking two most remote hydrants to hose connections &further hydraulic calculation and then finalized pump flow, pressure etc.
Sir ji pump room me 8 kg pressure hai to floor wise kitna kg pressure hona chahiye eska formula kya hai bataye na please...
Kg is not pressure unit. Kg may be mass or weight unit.
If you say 8kg/cm2 then it is unit of pressure.
Floor wise pressure can be calculate through hydraulic calculation and this calculation depend on pipe length, fittings, etc.
@@TanweerAhmed ye sir I say 8kg/cm2
If your pipe is straight vertical riser without bends then 1meter of water=1.4223psi or 2.3feet of water=1psi
what is the distance between
1. building peripheral area to hydrant post
2. and between hydrant post to next hydrant post?
Watch my hydrant installation video. Detail is given
Sir piller post hydrent ka daimiter kitne mm ka hota hi
Watch video complete, I have explained
Sir piller hydrant landing valve ko kitne hight me lagaya jata hai Land se
@@trilokisahu3 Watch my Installation of fire hydrant video
@@TanweerAhmed sir ji esme hydrent landing valve jo building k outer me laga hota hai uski hight land se kitne fit ka hota hai sir.... Ese video me nhi bataya hai sir please reply...
Same limit is used from minimum to maximum height
Can you please make video on As built drawings
What you want to know about As-built drawing?
great knowelge
Thanks
Good information Sir ☺️👍
Thank you 😌
can you guide minimum no of fire hydrants to be taken for calculation of fire flow.
Watch my videos "Fire Flow Requirements of Building" for detail information. While, minimum one hydrant can also be installed
Very well described
Thanks 😊

Hose connections minimum pressure is 100psi and maximum pressure is 175psi. Refer NFPA 14.
