Question

Explain how the cascade efficiency calculated?​

Answer 1

Answer:

The “well to wheels” efficiency of a typical gasoline-engine car is calculated from a similar cascade. Its “cascade efficiency” is even lower than that of an electric vehicle. The overall system efficiency, in this case, is 0.90×0.92×0.95×0.96 ≈ 0.76, or 76%.

Answer 2

Answer:

Generally, efficiency is defined as the ratio of output power to the input power. In Electrical Engineering efficiency is defined in terms of power or energy. Here,

Efficiency () = (Pout./Pin) * 100%
