Problem 21HP

Assume that the heat engine in Problem 5.34 has a high temperature of 1000 K and a low temperature of 400 K. What does the inequality of Clausius say about each of the four cases?

Problem 5.34

For each of the cases below, determine if the heat engine satisfies the first law (energy equation) and if it violates the second law.

a. ˙Q H = 6 kW, ˙QL = 4 kW, ˙W = 2 kW

b. ˙Q H = 6 kW, ˙QL = 0 kW, ˙W = 6 kW

c. ˙Q H = 6 kW, ˙QL = 2 kW, ˙W = 5 kW

d. ˙Q H = 6 kW, ˙QL = 6 kW, ˙W = 0 kW
