1" Water Pump

【WATER PUMP PRINCIPLE】

◎Calcuate the equivalent length(L) of the pipeline, in meters.
L  = L1 + L2 + K
L1 = Length of suction run from source to pump, in meters.
L2 = Length of pipeline from pump to outflow point, in meters.
K  = Pressure losses attributable to fittings. if any.

◎Calculate the total head(H) in meters.
H  = H1 + H2 + Pr
H1 = Suction lift, in meters, between water level and pump.
H2 = Discharge lift, in meters, between pump and outflow.
Pr  = Pressure required at outflow point, expressed in meters(1bar=10m).
