Pump Power Calc

Calculates hydraulic power (P_h = rho*g*Q*H), brake (shaft) power, and motor input power for a water or wastewater pump station at a specified duty point. Accounts for pump and motor efficiencies to determine the electrical power draw, following AWWA and Hydraulics Institute methodology for pump station design.
