Question

They create a heat engine where the hot reservoir is filled with water and steam at equilibrium, and the cold reservoir is filled with ice and water at equilibrium. What is the Carnot efficiency for their heat engine if the pressure is constant at 1.0 atmospheres?

Answer 1

The efficiency of Carnot's heat engine is 26.8 %.

Step-by-step explanation:

Temperature of hot reservoir, TH = 100 degree C = 373 K

temperature of cold reservoir, Tc = 0 degree C = 273 K

The efficiency of Carnot's heat engine is

`\eta = 1-(Tc)/(T_H)\\\\\eta = 1 -(273)/(373)\\\\\eta = 0.268 =26.8 %`

The efficiency of Carnot's heat engine is 26.8 %.
