Pump power calculation
I have the following situation:3 coolingwaterpumps, 3 different coolingwater users with gascoolers, coolingwaterpressure reading, coolingwaterflowreading.Can I use the formula as mentioned below for calculation of the pump power? We don't have an accurate powerreading on the pumpmotors, but we want to have an idea of the pumppower when changing the flow, pressure and when we do other adjustments in the coolingwater system. This is the formula:Ph =(q*rho*g*h)/3.6*10^6Pshaft = Ph/motorefficiencyunit's are in SI
(L/s)(m)(kg/L)(m/s2) = kg.m2/s3 = WQ
