Pump Hydraulic Efficiency is defined as below:
Use formula below to calculate the pump system efficiency:
Pump System Efficiency = Pump Hydraulic Power Output / Motor Shaft Power
Pump Hydraulic Power Output = (Flow Capacity x Head x Density x gravity) / 3.6 x 10⁶
Motor Shaft Power = Electrical Power Consumed x Motor Efficiency
Where:
Flow Capacity : In m³/h (Measured by flow meter Flexim F601)
Head : In m (Checked to the pressure gauge)
Density : In kg/m³ (Measured or checked to the Fluid Density Table)
gravity : 9.81 m/s²
Electrical Power Consumed : In kW (Measured by Power Logger Fluke 1735)
Motor Efficiency : In % (Checked to the nameplate or motor datasheet)
Use formula below to calculate the pump system efficiency:
Pump System Efficiency = Pump Hydraulic Power Output / Motor Shaft Power
Pump Hydraulic Power Output = (Flow Capacity x Head x Density x gravity) / 3.6 x 10⁶
Motor Shaft Power = Electrical Power Consumed x Motor Efficiency
