Figure below provides steady$-$state operating data for a solar power plant that operates on a Rankine cycle with Refrigerant $134$ a as its working fluid. The turbine and pump operate adiabatically. The rate of energy input to the collectors from solar radiation is $0\mathrm{.}3$ 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.
