Pump Head Calculation

Calculates total dynamic head for a pump duty point by converting suction and discharge pressure difference, pipe losses, and static elevation difference into metres of fluid head. The template also calculates hydraulic power from flow, fluid density, gravitational acceleration, and total dynamic head.
