Power is consumed by a pump, fan or compressor in order to move and increase the pressure of a fluid. The power requirement of the pump depends on a number of factors including the pump and motor efficiency, the differential pressure and the fluid density, viscosity and flow rate. This article provides relationships to determine the required …

This relates to small ore flow values. For the shaft power consumption of the machinery a parabolic-parabolic behaviour to the length of throw (L t) and reduction ratio (R) of the system is observed. Thus, the power consumption presents a maximum in an intermediate variable set located between at least two local minima.
