Obviously, that’s a fair amount of math to get at the pump efficiency, considering all of the units conversions that need to be done. The points of maximum efficiency are usually in the central sections of what is known as the efficiency curve, i.e., both on the left (start), where the pump delivers a lot of pressure but little flow — this being the most unstable working point of the whole system — and on the right, where we are approaching the maximum allowed consumption or even over.

In the u.s., ps is the power provided to the pump shaft in brake horsepower (bhp) and pw is: Because the pump power of n (kw) = (m) * head flow (m3/s) * 1000 (severe water / 102 (kg/m3) power conversion coefficient (eta), the efficiency of the pump, the pump efficiency) can be obtained.

Power input to pump = 1.732 * v * i * pf * motor efficiency * coupling efficiency. In this equation • the pump efficiency depends on the pump flow rate q pump (which is equal to the demanded flow rate) and in the case of variable speed operation on the rotational speed n (see sections 4.2 and 5.2 section 4.2 section 5.2).
