A solar collector and storage tank, shown in Fig. 8-15a, is to be optimized to achieve minimum first cost. During the day the temperature of water in the storage vessel is elevated from 25°C (the minimum useful temperature) to tmax, as shown in Fig. 8-15b. The collector receives 260 W/m² of solar ener- gy, but there is heat loss from the collector to ambient air by convection. The convection coefficient is 2 W/(m² · K), and the average temperature differ- ence during the 10-hour day is (25 + tmax)/2 minus the ambient temperature of 10°C. The energy above the minimum useful temperature of 25°C that is to be stored in the vessel during the day is 200,000 kJ. The density of water is 1000 kg/m³, and its specific heat is 4.19 kJ/(kg · K). The cost of the solar collector in dollars is 20A, where A is the area in square meters, and the cost…
