Consider a solar pond power plant operating on a closed Rankine cycle. Using refrigerant-134a as the workingfluid, specify the operating temperatures and pressures in the cycle, and estimate the required mass flow rate of refrigerant-134a for a net power output of 50 kW. Also, estimate the surface area of the pond for this level of continuous powerproduction. Assume that the solar energy is incident on the pond at a rate of 500 W per m2 of pond area at noontime, andthat the pond is capable of storing 15 percent of the incident solar energy in the storage zone
