Problem Statement A heat engine receives heat at a rate of 15 kW from a reservoir at 400 K. It delivers all of the shaft power it produces to a heat pump that delivers 25 kW of heat transfer to a reservoir at 350 K. The heat pump draws heat from a reservoir at 320 K. What is the temperature of the warmest region that the heat engine can reject heat to? Answer Table Stage Description 1 Max COP for heat pump 2 Shaft power (kW) 3 Max thermal efficiency of heat engine 4 Warmest region temperature (K) Your Answer Correct Answer * Due Date Grade (%) Part Weight Attempt Action/Message Type Nov 7, 2024 11:59 pm 0.0 1 1/5 Submit Stage 1 Nov 7, 2024 11:59 pm Nov 7, 2024 11:59 pm 0.0 1 1/5 0.0 1 1/5 Nov 7, 2024 11:59 pm 0.0 1 1/5
