Pump Sizing with Epanet

Pump Sizing with Epanet

Pump Sizing with Epanet

(OP)
I came across this instruction in Epanet Manual on "How to size a pump to meet a specific flow". After going through the procedure in the program, i ended up with an unusually high hydraulic head value at the discharge node. Could it be that i have misinterpreted the instruction?   

RE: Pump Sizing with Epanet

(OP)
Oops. Here are the instruction on the manual.

Set the status of the pump to CLOSED. At the suction (inlet) node of the pump add a demand equal to the required pump flow and place a negative demand of the same magnitude at the discharge node. After analyzing the network, the difference in heads between the two nodes is what the pump needs to deliver.
