Firefighting Lesson 1 | Sizing the pump for standpipe and fire hose system

[@jaredcarian6277]

Thank u very much..more of these please ut is very helpful for me as an ME

[@zian.2493]

Very informative video👍

[@turguthuseynov5230]

Maybe it is the best explanation, thank you!!! Really, but what about the sizing of pump, if that pump is serving FHC + SPRINKLERS AND + HYDRANT systems together ? Please, respond me

[@wawansharpone7341]

Excellent explanation and very usefull . Thanks a lot

[@AMJEngineering]

Thanks

[@Justlikethat2030]

Thank you so much for this video.what if there is a single main line having 52 Hydrant( class 1) for 6.5km long road tunnel( elevation from one portal to the other is 145m , uniform gradient). How will then we calculate

[@paulomorales6505]

Thanks a lot.Good explanation at all. What about the sizing of pump with sprinklers and stand pipe? Or we just need to sum sprinkler hydrauclic calculation + hydraulic calculation of stand pipe? Hoping you will notice me

[@AMJEngineering]

Yes you have to sum it.

[@ironmatic1]

No. Whichever is greater, which is usually standpipe demand.

[@darrelluzon5283]

great video. But why does the diameter of the pipe changes from 6 inches to 6.065 inches?

[@AMJEngineering]

6 inches is the nominal diameter size. for friction loss calculations you have to consider internal diameter.

[@bagusbudi3018]

Hi sir, thanks for the video. just a question in 05:19 where did the 0.00271 came from?

[@AMJEngineering]

refer to 3:47, it is friction loss in pipes

[@demonic__afzuu7554]

Hi what does inside and outside hose meaning ??

[@salehshati1902]

ty

[@MuhammadJawad-mx3yh]

Such a wonderful explanation, much appreciated keep it up. if there is one riser serving 9 floors of building and each floor has 4 fire hose cabinets, then what would be the size of main riser a/c to NFPA?

[@ironmatic1]

according to your hydraulic calculations...

[@m.arahman4731]

Thanks

[@AMJEngineering]

welcome👍

[@mohammedmalik9311]

Please how u convert static head from 20 meters to 29.4 PSI

[@AMJEngineering]

10m water height means 1 bar pressure. 1bar = 14.7 psi

[@bimafernand4860]

please tell how to get 0.00271 psi and 0.00075 psi ? thank you

[@Mrhandyhitman]

The 1250 GPM is only for non sprinkled buildings just an fyi

[@djestengineer8342]

Please explain how to get 0.00271 psi & 0.00075 psi. Thank you

[@AMJEngineering]

refer to 3:47 friction loss formula

[@ajaysherekar6539]

Very informative video but for begineers its too fast. Need to slow down to understand all aspects.

[@keiramcdonald8802]

Is this American or British?

[@karthikk3192]

Mostly America follows NFPA code and UK with BS EN 12845 code

[@AMJEngineering]

yes it is American

[@HoraceHingCheungPoon]

Any certificates?

[@rinsonjacob9408]

Sorry. I dont have basics. Thats why i dont understand anything. Any suggestion to read basics.
