NAME: OSU ID: A reversible heat engine operates between two thermal reservoirs, with temperatures of and 400 °C. The net power (electrical work) output of the cycle is 1 kW. What is the heat input to the cycle? 3. 20°C (A) 1.05 k W (B) 0.56 kW (C) 1.79 kW (D) Not enough information
5-6 Figure 5-6 shows the schematic diagram for a two-stage cascade refrigeration system. Each stage operates on an ideal vapor-compression refrigeration cycle with refrigerant- 134a as the working fluid. All the important data and refrigerant phases are given in the schematic diagrams. By referring to the diagrams, determine: (a) The ratio of mass flow rate of the system and draw a T-s diagram complete with the data given. Enthalpy values for each states. Compressor power input for Cycle A and...
