Water flows out of the system through sprinkler, pumps will be continuous running and no chance to build up the pressure in system with fused sprinklers. In this case how main pump will auto swith off and reaches the cut off pressure.
Nice video dear sir , but what i got the churn pressure is pr at which pump is runing with water and gate valve at discharge pump line is completly closed , So if we run the pump at 100 % flow capcity with closed Gv at discharge then pump will get heated , and bez of the K.E is converting into heat , there is a relife vlave line to atm with small dischage line to cool the pump casing , but for how long we will run the pump , if we run too much pump will burn , so is it for 30 sec , AND FOR THE FITTING AFTER THE discharge of pump does it has to with stand pr = or > than churn pr rating while selection this will increase the cost of material , Is it like that fittings near the pump discharge line we consider pr rating of it to be churn pr , and for fitting far a way from pump room we consider it to withstand normal pump pr , as pr decrese as we go far a way from pump room
@@TanweerAhmed thank y , but still i have one point that , if we are taking churn pr to be with standing pr for fittings in system , so while the main pump start set point = jockey start pr - 5 psi = 155 psi - 5 psi = 150 psi So it means when the main pump will start it will exert a pr of 150 psi on all fitting , and we considered the fitting working pr to be churn pr = 115 psi , Isnt in this case the fitting will fail
Very nicely explain, thanks only if you have underground supply tank for water then ....? Mostly water supply for this part of the world with fire water tank, please explain .
Assalamo alaikum, I have one question - as per nfpa setting that you explain above, in middle east countries this setting is not followed. For example if a pump is 750 GPM @ 100 psi then can you explain what will be the pressure setting for jockey pump and electric pump ?
@@TanweerAhmed sir...humble request, can you please make videos on types of commodities, storage , and few examples for calculation of CMDA, CMSA and ESFR sprinkler in warehouses with in rack sprinklers and various occupancies sprinkler design requirements, miscellaneous storage and calculation of sprinkler and water supply requirements as per NFPA 13 in your upcoming videos, if you have already made please share the link sir....I gain a lot...and you make learning fire protection topics very easy..thanks sir.. ❤️
Sir please answer my question. Line pressure will be always less than churn pressure due to frictional losses . All Fire pumps start and stop not to be based on actual line/pipe pressure instead of churn pressure since actual line pressure is far less than churn pressure due to losses Darcey law ? . Here I am considering Churn pressure is the pressure at pump discharge line when gate valve is fully closed i.e. max pressure. Please guide me.
Dear sir fire pump room ke air vessal tank ki video bna dijiye,or ye concept bhi clear kr dijiye ki pump room ke air vessal tank me arv lgegi ya prv...pls
@@TanweerAhmed sir pls jald se jald bna dena,kuch or doubt bhi hai aap unhe bhi clear kra dena 1. hmara main pump auto start pr manual bnd hota hai, fire-fighting ke doran start ho gya or hmari fire-fighting bhi complete ho gyi pr hmne pump ko manual band nhi kiya,to kya line fat jyegi ya phr pump me koi or device lgi hoti hai jisse line damage na ho...? Air vessal tank me prv lgegi ya arv ? Re circulation valve kha lga hota hai ? Pls sir inke bare me knowledge de dijiye...
1. Pressure relief valve is installed at pump discharge for relieving excessive pressure from set or cut off value. Moreover, pump head is design for centrifugal fire pump which does not increase head pressure from design, therefore no problem of pipeline damages.
Air Vessel Tank is an expansion tank or expansion vessel is a small tank used to protect closed (not open to atmospheric pressure) fire or chilled or domestic water systems from excessive pressure. The tank is partially filled with air, whose compressibility cushions shock caused by water hammer and absorbs excess water pressure caused by thermal expansion. Therefore, in this tank only air filling with air release valve.
Great videos. I have a question regarding the static pressure alowen(maximum) for high-rise building. How many statics does fire pump can carry? Thanks
What if the churn pressure are different for electric and diesel pumps ? Which pump churn Should be taken as reference ? Is this setting mandatory as per nfpa?
@@TanweerAhmed thanks for the reply … u r doing a great job .. could you pls do a video on foam fighting line with a drawing so as to clear all the components in the system
@Tanweer Ahmed sir very helpful, i have a question. What is the suction pressure in case of u.g.w.tank . What would be the jockey pump stop if fire pump is 500gpm and 225 psi head ?
In this condition, no city water and underground tank therefore suction pressure consider zero or negative as per site condition. If considering zero then jockey pump stop 225psi if head is calculated correctly and then jockey pump start 225-10=215psi and fire pump start 215-5=210psi
Sir me india se hu me apke Sare video Dekhta hu me plumbing or fire cad service line me hu sir maine bhut se engineers ke under me work kiya hai lakin app jaisa explain koi karta ho aisa deep knowlege bhi kisi ko ho slute hai sir apko 🙏
Thanks, Electrical & Diesel both are same capacity pumps and both are main pumps but normally electrical available 24hrs from government sources for private sources then electric pump consider as a main pump while diesel pump consider as a standby pump because diesel pump use rarely, in case power not available

Sir, for example rating of electric pump discharge 2280 LPM & head 80 m then what will pressure setting??. If discharge 2850 LPM & head 80 m then pressure rating change??
It is used for pressure. Mostly this switch is used with fire pump controllers/panels and liquid pipe line connect with transducer switch and panel indicate pressure of fire pipelines.
Jockey pump start and stop at Delta 10psi difference of Pump head pressure. Head pressure is written on name plate of fire pump which is calculate according floor height, pipes, fittings, horizontal lengths, valves etc. as per site or drawing.

JazakaAllah, this is NFPA recommendations pressure setting for fire pumps. All fire pumps run and stop automatically except diesel fire pump.
Water flows out of the system through sprinkler, pumps will be continuous running and no chance to build up the pressure in system with fused sprinklers. In this case how main pump will auto swith off and reaches the cut off pressure.
Do we need to manually switch of the pump after fire case
Very good video

Good sir ,its very useful

Sir u r great
Welcome
Nice video dear sir , but what i got the churn pressure is pr at which pump is runing with water and gate valve at discharge pump line is completly closed ,
So if we run the pump at 100 % flow capcity with closed Gv at discharge
then pump will get heated , and bez of the K.E is converting into heat , there is a relife vlave line to atm with small dischage line to cool the pump casing , but for how long we will run the pump , if we run too much pump will burn , so is it for 30 sec ,
AND FOR THE FITTING AFTER THE discharge of pump does it has to with stand pr = or > than churn pr rating while selection this will increase the cost of material ,
Is it like that fittings near the pump discharge line we consider pr rating of it to be churn pr , and for fitting far a way from pump room we consider it to withstand normal pump pr , as pr decrese as we go far a way from pump room
You got right from my point of view but it is NFPA standard requirements
@@TanweerAhmed thank y , but still i have one point that , if we are taking churn pr to be with standing pr for fittings in system
, so while the main pump start set point = jockey start pr - 5 psi
= 155 psi - 5 psi = 150 psi
So it means when the main pump will start it will exert a pr of 150 psi on all fitting , and we considered the fitting working pr to be churn pr = 115 psi ,
Isnt in this case the fitting will fail
In firefighting, fittings are used PN25, it means fitting can sustain 250psi nominal pressure
dera sir can you make one video abut diesel pump battery capcity
Battery capacity decided by generator manufacturer there I don't know more about it
Very nicely explain, thanks only if you have underground supply tank for water then ....?
Mostly water supply for this part of the world with fire water tank, please explain .

What do you mean for fire it is either electrical pump or diesel pump
A fire pump is NFPA wording, its means pump used for firefighting
