A steady-state system for producing power consist of a pump, heat exchanger and a turbine. Water at 1.0 bar and 20°C (state 1) enters the adiabatic pump and leaves at 10 bar (state 2). The pump draws 110 kW of power, and the mass flow rate of water is 45 kg/s. The water leaving the pump enters a heat exchanger and heated at constant pressure to 400°C (state 3) using exhaust gases (Cp of gases = 1.1 kJ/kgK) that enters at 500°C and exits at 182°C. The steam is adiabatically expanded in a turbine having an isentropic efficiency of 0.71. The turbine exhausts (state 4) to the surroundings at 1.0 bar. What is thermal efficiency of this power production process? If the pump and turbine are reversible, would the efficiency of this system equal the maximum possible efficiency? (Answer Yes or NO and provide a short explanation.)

2 kg of Refrigerant-134a contained in a piston-cylinder device undergoes a reversed Carnot cycle. Some important information about the cycle is: ● At the beginning of the adiabatic compression (State 1), the refrigerant is a saturated vapor. ● The adiabatic compression ends when the temperature of the refrigerant is 30 degrees C● The refrigerant is 50% vapor by mass at the end of the isothermal heat rejection process. ● The adiabatic expansion process ends when the pressure of the refrigerant is 132.82kPaConsulting example 7-6 in your text might be helpful in understanding some aspects of this problem. a) Represent this cycle on a T-S diagram.

A fluid at 0.6 bar occupying 0.07 m3 is compressed reversibly to a pressure of 9.5 bar and specific volume of 0.3 m3/kg according to the law pvn = c. The fluid then expands reversibly according to the law pv2 = c to 2.3 bar. A reversible cooling at constant volume then restores the fluid back to initial state. Calculate the work for the compression in the process.
