Question:
Consider the four cases of a heat engine in Problem 5.34 and determine if any of those are perpetual machines of the first or second kind.
Data from 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
