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.
01/01/2016· To calculate the operating work index the work input is obtained from the mill power which, if obtained from the motor power, has to be the power at the mill pinion shaft. That is, if adjustments were coupled directly to the pinion shaft, then motor output power is the mill pinion shaft power. Work input is then obtained from the mill power (kW) by dividing it by the circuit throughput (t/h).

Calculation of Agitated Liquid Batch Power Numbers To determine the power delivered to a given fluid at a set rotational speed, several other variables are also required. These variables relate to the vessel geometry and other "shape" parameters. A number of benchmark studies were done by J. H. Rushton, Reference # 10, in the 1950''s to correlate power number with know vessel _____ Page 5 ...
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.

The shaft power produced by an electric direct current motor with 36 V, 85% efficiency and 5 amps can be calculated in watts as Pshaft_kW = (36 V) (5 amps) / 1000 = kW = 153 W
To calculate shaft power (SP), you need to know the torque (T) and the shaft speed (w), the latter in radian/sec. To get the shaft speed, w w = (2*pi/60)*(rpm) [rad/s] and shaft power is SP = w * T [=] (rad/s)*(ftlb) = ftlb/s or [=] (rad/s)*(mN) = mN/s = J/s = W To get shaft horse power, it is only necessary to convert ftlb/s to hp. Brake power (whether in ftlb/s or W) is shaft power ...
