Engine efficiency equation
WebJul 1, 2024 · Energy efficiency is the ratio or useful energy to input energy. efficiency = (useful energy / input energy) × 100For example, a solar panel that creates 300 watts of electricity from 1500 watts of sunlight:efficiency = (300 /1500) × … WebΔ W is the total mechanical work: Δ W = W 12 + Δ W 34 = − n R ( T 2 − T 1) ln V 2 V 1. So finally the efficiency is. η = T 2 − T 1 T 2 + C V ( T 2 − T 1) n R ln V 2 / V 1 < η C. It is …
