Pump Power for Flow between Two Reservoirs

 

A pump transfers liquid from one tank to another according to the following schematic, with check valves placed on either side of the pump. Each tank is open to the atmosphere.  This worksheet calculates the flow rate in the pipe by solving the Bernoulli equation for the system, taking into account the head added by the pump, and the head loss due to friction and pipe fittings.
