Pump Head And NPSH Calculator
Pump Head And NPSH: a planned Super Calculator tool. Covers flow rate. Stub page: the tool, its formula and a worked example are not published yet. Scope is.
Pump Head And NPSH Calculator is a planned calculator in the engineering section of Super Calculator, covering building services engineering.
What this calculator will compute
Inputs: flow rate, static suction and discharge heads, pipe sizes and lengths, fittings, fluid and temperature, elevation, pump efficiency and NPSH required.
Outputs: total dynamic head, hydraulic and shaft power, motor size, NPSH available and margin, cavitation warning and operating point on a system curve.
Formula, recorded as scope and not yet verified against a primary source: Total dynamic head = static lift plus friction loss plus velocity head plus pressure head difference. Hydraulic power P = rho g Q H, divided by pump and motor efficiency for shaft and input power. NPSH available = atmospheric head plus static head minus vapor pressure head minus suction friction, and must exceed NPSH required with a margin.
