Question
SL-3 A refrigerator with K-4 and a reversible heat engine operate between two heat reservoirs at 300K and 400K. During each cycle of operation the engine produces 500J of work, which is the entire work input to the refrigerator for each cycle. a) Write down or calculate the magnitudes of the Wk, Q, and Qe for one cycle of operation of the engine. b) Write down or calculate the magnitudes of the Wk, Qh, and Qe for one cycle of operation of the refrigerator. c) Calculate the magnitudes of the Wkecl, Qhnet, and Qenet for one cycle of operation of the system. d) Show on a diagram like the one above for problem SL-1 the energy flow for the engine and refrigerator individually on the left and the net energy flow for the engine-refrigerator system on the right. e) Does this net result violate the second law of thermodynamics? EXPLAIN your answer.
