Problem 3 Figure 3 shows a system for collecting solar radiation and utilizing it to produce electricity by a power cycle. The solar collector receives solar radiation at the rate of 0.315 kW per m² of area and provide energy to a storage unit whose temperature remains constant at 500 K. The power cycle receives energy by heat transfer from the storage unit, generates electricity at the rate of 570 kW, and discharges energy by heat transfer to the surroundings at 20°C. Solar radiation Solar collector Surroundings at 20°C Power cycle Storage unit at 500 K Area a) Draw a simple schematic of this power cycle, identifying the cold and hot reservoirs and the directions of the heat transfer in both reservoirs, and of the work b) What is the theoretical maximum efficiency of this power cycle? c) What is the minimum collector area required for this system? d) What is the heat transfer rates in the cold and hot reservoirs associated with maximum efficiency e) Suppose the efficiency of this power cycle is 0.32. Is this efficiency possible? Why or why not? If the answer is yes, what would the heat transfer rates be in the hot and cold reservoirs and what would be the collector area for this scenario?
