Thanks for the video. I have a question regarding Node2. why don't you consider anty fitting in node2? I think there is a fitting between Node 2 and Node A that needs to be added as a fitting in Node 2 calculations. Please correct me if I am wrong.
Hoping for hydraulic calculation of the entire drawing as it is (incorporating the remaining branches at the laundry station as well ). Thank you for this explanation.
Thank you for the video, it is really interesting but I have some questions 1. How many sprinkler you assume to operate because I saw in the calculation sheep you calculate only 2 sprinklers then you continued to calculate to CM...? 2. To me, I choose 12 sprinklers for operating so do I need to calculate for all 12 sprinklers? Thank you in advance
Good explanation. It would be more understandable if u had used autocad isometric layout with nodes and input those data in elite software and run the calculation....
Hello sir, Thanks for the knowledge shared. I hope you will share for stand pipes also. I will be pleased if you share hydraulic calculation basics for complete fire fighting system.
Hi Sir, thanks for the Video. I have a question, hope you can share your opinion. The sprinkler hydraulic calculation is calculated at the most remote area of the building from the Fire Pump. If at the furthest area, i have -example-10 branch (each branch = 10 Sprinkler) and refer to rules of Ordinary Hazard 2, 1500 ft2 @ 0.2 gpm/ft2, i only get 2 branches covered at 1500 ft2. So is it correct, the fire pump sizing will only depend on these 2 branches and its header and ignoring the other branches or the other room which are near to Fire Pump. Thankss
The concept is right as u said . But I say u must follow the NFPA 13 guide lines how to consider the remote area.as I remember there is a format to select the design area.
can you please share the info about K factor and X factor of deluge valve used in hydraulic calculation .from where we can get this info and how to calculate. appreciate your response
Thanks this video was very useful, My question is that you have calculated the flow and pressure for one side sprinkler of cross main how about the other side
Not sure if this has been answered. In NFPA 13 standards, you only have to cover 1500 sq feet, so you will not need to cover on the other end of that main due to it falls out of the remote area. If you lay out the remote area, and the end of the line of the area falls more than half way into another sprinkler head, you have to pick up the next sprinkler head.
Glad that you enjoyed it! The parameters are in the interest of the designer. And several factors could determine them... But again, if you are designing these systems, you'll definitely know what the parameters are...
question sir? how about the other heads branch below base on your plan ,you just consider the upper heads and compute the cross main pipes pressure. TY
Principle of the remote area is if u supply the required flow and pressure to the sprinklers in remote area its logic that all other sprinklers in the pipe network will attain more pressure compare to them.
Hi Suhail! In the sample calculation, the fitting used is a 2-in fitting; hence, the 10ft equivalent length. Regardless of whatever fitting you use, when you do your design calculation, just make sure that you use its equivalent length as per NFPA13, Table 14.4.3.1.1. Thanks for watching, and asking! hehe keep them coming! ;)
Hi! I'm happy that this has helped you. I would be glad to have a look at your project and see what I can do. Here's my e-mail: marcbryan.vargas@gmail.com
HOW did u decide the diameter of the pipes. i mean you have done hydraulic calculation assuming the diameters as 25 mm, 32 mm and so on but how did we arrive at the sizes?
U need to refer nfpa 13 pipe sizes table for light,ordinary and extra hazard table. Use these pipe data and input them in elite software and run it. If there is more friction losses the software will intimate you which pipe needs to be resized to attain the minimum design parameter set by NFPA13
Not sure if this is answered however K-factor is based on the fire sprinkler listing. To get that you need to look at the spec sheet of the sprinkler head you are using.
Sir, I thought that in node C there will be a pressure loss due to elevation since it is connected to a 100ft riser. Can you be so kind to explain to me otherwise? Thanks a lot!
regarding hose connection. Fire hose has a min. working pressure of 100 psi right? you didn't include it in the calculation for the pressure of the hose?
@@marcbryanvargas4673 why on your calculation the total psi was only around 10 psi? you only include the flow for the allowable hose stream connection. it should have been 110 psi?
@@ben-hurrocillo1645 Hi Jecelle, thanks for pointing this out! I've checked my calculations again and I did overlook it. I'll have an erratum on this in an upcoming video... I really appreciate your feedback. Once again, thanks!
@@marcbryanvargas4673 thanks also. I've seen a lot of hydraulic calcs that doesn't conaider the pressure for the fire hose. So I thought they didn't consider the 100psi requirement for fire hose. Thanks for verifying that it should be included on the calcs.

HOW did u decide the diameter of the pipes. i mean you have done hydraulic calculation assuming the diameters as 25 mm, 32 mm and so on but how did we arrive at the sizes?
The diameters of the pipe in this problem are given parameters. Ideally, pipe sizes should be determined after calculating the flow rate...
U need to refer nfpa 13 pipe sizes table for light,ordinary and extra hazard table. Use these pipe data and input them in elite software and run it. If there is more friction losses the software will intimate you which pipe needs to be resized to attain the minimum design parameter set by NFPA13
Hi Sir, how do I select the right K-factor? is 4.75 a standard?
