Determining Electric Motor Load and Efficiency
Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor 's efficiency tends to decrease dramatically below about 50% load. However, the range of good efficiency varies with individual motors and tends to

How do you calculate water turbine efficiency? If you don't mind equations the easiest way to explain how much power you could generate is to look at the equation for calculating hydropower: Hnet = Hgross x 0.9 = 2.5 x 0.9 = 2.25 m. 3 m3/s = 3,000 litres per second. Power (W) = m x g x Hnet x η = 3,000 x 9.81 x 2.25 x 0.751 = 49,729 W = 49.7 kW.
