Solve the following showing all diagrams ( flows and labels ) and assumptions made. You have a hot reservoir (TH) at 1500 K and a cold reservoir (TC) at 300 K. A. Find the maximum work from an engine, operating between these temperatures, if the heat transfer from the hot reservoir is 2000 kJ? B. Determine whether the following heat engines, operating between these temperatures, obeys or breaks the first and second laws of thermodynamics: (1) QH = 1000 kJ ; QC = 500 kJ; W = 500 kJ (2) QH = 1000 kJ ; QC = 1200 kJ; W = 200 kJ (3) QH = 1000 kJ ; QC = 200 kJ; W = 800 kJ
