Pump Head Calculator

Calculate total dynamic head from static head, pressure requirement and friction losses.

Calculator

Total dynamic head (Htotal)

Formula

The total dynamic head is calculated as:

Htotal = Hstatic + Hpressure + Hfriction + Hreserve

Where:

  • Hstatic = discharge level − suction level [m]
  • Hpressure = required pressure converted to liquid head [m]
  • Hfriction = pipe and fitting losses [m]
  • Hreserve = additional margin or process allowance [m]

Engineering note

This is a practical preliminary TDH calculation. For final sizing, friction losses should be calculated from the actual pipe route, fittings, valves, flow regime and fluid properties.
