Question

You are asked to assess the validity of a power-generating device. The device supposedly operates steadily by receiving 256 kW via heat transfer at 4.5 °C, receiving 370 kW via heat transfer at 115 °C, and rejecting 200 kW via heat transfer at -180 °C. The device generates electrical power in response to these various heat transfers.

a. determine its electrical power output, in kW.

b. Is the device feasible? Does it violate 1st and/or 2nd law of thermodynamics?

T = 115 C Q = 370 KW T = -180 C Q = 256 KW T = 4.5 C Q = 200 KW +
Transcribed Image Text:T = 115 C Q = 370 KW T = -180 C Q = 256 KW T = 4.5 C Q = 200 KW +
