19/1/2016, · ,The efficiency, factor is found from a graph by taking G HP divided by API gearbox-torque rating and then intersecting either a worn- or new-unit ,efficiency, curve. This ,efficiency, factor is applied to the P HP to convert it to B HP at the prime mover and is required to offset power losses caused by friction in the surface equipment.

Part 7: Pumps and Turbines – The Bernoulli Equation | ITACA

If you know the power (W out) that is delivered by a pump, then it is possible to calculate the pressure it represents (P p ). Thus the energy the pump provides as a pressure (P p) is given by: Typically pumps have an efficiency (γ)which is the ratio of the power out (W out ) to the power in (W in ).
