Calculate the efficiency of a reversible heat engine working between temperature 100 degree Celsius and 0 degree Celsius
Answers
The efficiency of a reversible heat engine working between given temperature is 26.81%.
Explanation:
=> Here,
Temperature of sink in kelvin, T₂ = 0° C = 273 K
Temperature of source in kelvin, T₁ = 100°C = 273 + 100 = 373K
=>Now, the efficiency of a reversible heat engine, η:
η = 1 - T₂/T₁
= 1 - 273/373
= 1 - 0.7319
= 0.2681
= 26.81 %
Thus, the efficiency of a reversible heat engine working between given temperature is 26.81%.
