Thermal efficiency - (Principles of Physics I) - Fiveable
Thermal efficiency is calculated using the formula: $$ ext {Efficiency} = \frac { ext {Work Output}} { ext {Heat Input}} \times 100$$. Real-world engines often operate at thermal efficiencies significantly lower than the theoretical maximum due to irreversibilities and friction in the system.
Thermal efficiency - Simple English Wikipedia, the free …
For an energy conversion device like a boiler or furnace, the thermal efficiency is. So, for a boiler that produces 210 kW (or 700,000 BTU/h) output for each 300 kW (or 1,000,000 BTU/h) heat-equivalent input, its thermal efficiency is 210/300 = 0.70, or 70%. This means that the 30% of the energy is lost to the environment.
