Figure P8.13 provides steady-state operating data for a solar power plant that operates on a Rankine cycle with Refrigerant 134a as its working fluid. The turbine and pump operate adiabatically. The rate of energy input to the collectors from solar radiation is 0.3 kW per m^2 of collector surface area, with 60% of the solar input to the collectors absorbed by the refrigerant as it passes through the collectors. Determine the solar collector surface area, in m^2 per kW of power developed by the plant. Discuss possible operational improvements that could reduce the required collector surface area.

Need help with this engineering problem.   Steam enters the turbine of a simple vapor power plant with a pressure of 12 MPa and a temperature of 500°C and expands adiabatically to condenser pressure, p. Saturated liquid exits the condenser at pressure p. The isentropic efficiency of both the turbine and the pump is 84%.For p = 100 kPa, determine: (a) the turbine exit quality, in percent.(b) the cycle thermal efficiency, in percent.

A binary vapor power cycle consists of two ideal Rankine cycles with steam and Refrigerant 134a as the working fluids. The mass flow rate of steam is 2 kg/s. In the steam cycle, superheated vapor enters the turbine at 8 MPa, 560°C, and saturated liquid exits the condenser at 50 kPa. In the interconnecting heat exchanger, energy rejected by heat transfer from the steam cycle is provided to the Refrigerant 134a cycle. The heat exchanger experiences no stray heat transfer with its surroundings. Superheated Refrigerant 134a leaves the heat exchanger at 600 kPa, 30°C, which enters the Refrigerant 134a turbine. Saturated liquid leaves the Refrigerant 134a condenser at 100 kPa.Determine:(a) the net power developed by the binary cycle, in kW.(b) the rate of heat addition to the binary cycle, in kW.(c) the percent thermal efficiency of the binary cycle.(d) the rate of entropy production in the interconnecting heat exchanger, in kW/K.
