You are designing a heat recovery system for a new autonomous Mars rover. The system currently uses freon as the heat transfer fluid. The system must maintain an instrumentation temperature of at least−67◦Fin an environment of 189K. If the system needs to move47.4BT U, what volume of working fluid is needed in units ofL? Note that freon has a specific gravity of 1.49, a molecular mass of 120g/mol, and a specific heat of 74J/(molK)

7-75 Reconsider Prob. 7-73. Now, it is proposed that the liquid water coming out of the separator be used as the heat source in a binary cycle with isobutane as the working fluid (Fig. P7-75). Geothermal liquid water leaves the heat exchanger at 90°C while isobutane enters the turbine at 3.25 MPa and 145°C and leaves at 80°C and 400 kPa. Isobutane is condensed in an air-cooled condenser and then pumped to the heat exchanger pressure. Assuming an isentropic efficiency of 90 percent for the pump, determine (a) the mass flow rate of isobutane in the binary cycle, (b) the net power outputs of both the flashing and the binary sections of the plant, and (c) the thermal efficiencies of the binary cycle and the combined plant. The properties of isobutane at various states in the cycle are h, = 755.05 kJ/kg, h, = 691.01 kJ/kg, h = 270.83 kJ/kg, and h,, = 276.65 kJ/kg.
