Pump Efficiency Calculator
Input Electrical Power (kW)   Flow (l/s)
Inverter Efficiency (%)   Head (m)
Motor Efficiency (%)   Pump Input Power (kW)
      Fluid Power (kW)
Pump Efficiency (%)      
'Wire to Water' Efficiency (%)        
How to Use the Calculator:
Enter your measured Input Electrical Power, Inverter Eff, Motor Eff, Flow and Head to calculate your Pump Efficiency and Overall 'Wire to Water' Efficiency.
1. Inverter Efficiency is difficult to measure. In most cases it is around the range 95%-98%.
2. Motor Efficiency is also difficult to determine in isolation. Use estimates around 90% for more recent higher efficiency motors.
