2. Calculation of hydraulic and shaft power How to calculate the pump hydraulic power ? The hydraulic pump power calculation is done thanks to the pump flowrate, the pump head and the density of the fluid being pump. Pump power formula is the following : P hydraulic = ρ/367. In case the density is changing significantly when the fluid goes through the pump, the density at the inlet is used.

WhatsApp When a shaft is transmitting a power from driver equipment to the driven equipment, It is necessary to calculate the shaft diameter from the torque based on the maximum torque that can be transferred through the shaft or the maximum amount of twist in the shaft. Otherwise, the shaft may not satisfy the functionality of the equipment.
