JG, the way to calculate the power before losses, if the power after losses is 113 kW and losses are 25% is as follows:JG Shields wrote:25% on top of 113 = 141
Power at flywheel x (100% - loss%)/100 = 113
Or
Power at flywheel = 113 / [(100% - loss%)/100] = 113 / 0.75 = 151 kW
Remember that the power loss must be calculated based on the power before losses, not after.
