Ok guys I'm not familiar enough with power source requirements so looking for guidance. I have a client trying to some how get out of buying the Fire Pump with a transfer switch. This is located in Cambodia so it's not looking good. It's in the capital but because I live here so I know they ha

E.G like this: 5/.433=11.547 ft of head "h". From experiments: v=SQRT(2gh), so if you are getting a 5 on the pitot gage it means the water is going (2*32.2*11.547)^.5=27.27ft/sec. Now if we just knew what the reduction in the effective square feet of the 2.5 orifice was, we could start calcing s

I just ran this very thing by the forum. The consensus was the barrier has to isolate the shower enclosure from the wall cavity so the sheet rock would have to be on both sides of the stud. Ron F -Original Message- From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.

I'm looking for a quick sanity check. We are an A/E firm designing new college dormitories. These dorms typically contain four bedroom suites with two bathrooms in each suite. The 1987 edition of 2013 is applicable, and the bathrooms are less than 55 square feet. In order to omit sprinklers

Hmmm.. I wonder if there is any way we can figure out how fast water would have to be going to exert a velocity pressure of 5 psi? Could we slap ourselves on the forehead and say Hey- the old Law of Falling Bodies works here. ? > On May 15, 2014, at 11:06 AM, wrote: > > Tim, So based on 47 psi

Tim, So based on 47 psi at one test valve and just a flow on the rest, what was the pressure on the suction flange of the pump? Can't you just plot 1500 gpm on flow test curve and subtract the friction and elevation losses between the supply and pump? Brian, Pitot the discharge for each outlet

RE: Test Header Calc

2014-05-15 Thread Craig.Prahl
Are you trying to determine a pressure so you can assign a k-factor to the test header outlets? Why not just put a fixed flow from each test connection outlet and then see what the pressure is and how that compares to the pump rating? Do you have a flow test showing what's going into the pump?

You can play "what-if" scenarios all day long. Some issues such as those listed below were due to poor plant operations protocols. Storing hazardous materials adjacent to the fire pump house doesn't meet the requirements of NFPA 20, 4.12.1 which states; "The fire pump, driver, controller, wate
