Is there a formula to calculate the residual pressure needed to flow a specific amount of Water through a fixed orifice size.
I am up in Canada and cannot do a residual flow test on a fire hydrant until next spring.
I do however have water flow information from the fire dept in US gallons per minute. When they fill their pumper truck through a storz connection with an internal dimension of 3-1/2" they are able to flow 825 US gal per minute. Is there a formula that would be able to tell me what the residual pressure would be to achieve this flow rate?
