How is engine power measured

WebIn a series circuit Z = √÷R2, where X is the inductive or capacitive reactance in ohms and R is the resistance in ohms. In a parallel circuit Z = RX/√÷R2. Power factor is the ratio R/Z. Power factor can also be described as the true power divided by the apparent power: PF = W/VA. For a purely resistive circuit, PF = 1. Web250, but that the engine is putting out about 380 HP at that same speed. What happened to the missing 130 horse-power? The answer is that the engine isn’t generating it. A diesel engine’s power at any RPM is controlled by how much fuel is metered into the injectors. This engine could produce 380 HP at 2,300 RPM, but since the propeller is ...
