WebNov 13, 2013 · For operation of the plumbing system, you would use the residual pressure to determine pressure loss at the design flow in the system piping to determine if adequate water pressure is available for fixture use. Flush valves, for instance have a pressure requirement at a certain flow (25 gpm at 35 psig in the IPC).
Residual Pressure Formula For a given flow system, the residual pressure ( Pres) in psi, is a function of the static pressure ( Pstat) in psi, the flowrate ( Q) in gpm, and a constant ( K) that indicates flow capacity. The constant K is unique to each flow system and carrying out a flow test determines it.
