Q1. Solve all parts Depicted in Fig. Q1 is an irreversible refrigerator whose compressor is powered by a reversible heat engine that operates between temperature extremes Thot = 473K and cold = 293 K. The refrigerator depicted uses a dichlorodifluoromethane refrigerant (Refrigerant 12) circulating by means of the compressor at mass flow rate = 0.15 kg/s. The other components of the refrigerator are two heat exchangers in the form of an evaporator and a condenser, and a throttle valve. Information recorded at the state points depicted in Fig. Q1 is as follows: State point 1: dryness fraction x₁ = 1 and temperature t₁ = 15 °C. State point 2: dryness fraction x2 = 0 and temperature t₂ = 15°C. State point 3: wet vapour at temperature t₁ = -20°C. State point 4: wet vapour at temperature t₁ = -20°C.

A heat engine has a net work output of 500 MW. It receives thermal energy from water traveling through the core and exiting as a saturated vapor (note pressure of the core is 7 MPa. That steam then travels to a condenser where the output is a saturated liquid. The waste heat is discharged to a nearby body of water at 17°C. For steady state operation, determine the minimum theoretical steam mass flow rate in kg/s required to achieve the heat engine output.
