Can anyone explain the concept of "contination pressure" to me regarding fire pumps. The first time I've seen this term is in Hydracalc and I really don't grasp it. Let' say I have a pump rated 125 psi @ 1000 gpm. (churn is at 147 psi) my system demand is 98 psi @ 481 gpm at the pump discharge. The report spits out the proper system demand pressure followed by: "Continuation Pressure: 186.7, Pressure @ pump outlet 186.7 Pressure from pump curve: 146.0" etc...
Any hydracalcers care to take a stab at this? Am I missing something, doing something wrong, or is it too close to friday? I always thought max pressure would be the pumps churn - not a continuation of pressure off the curve somewhere in space?
