- Good Day , Am struggling with the two questions below , please assit Question 1 A solar-power-tower plant is considered for Dakar, Senegal. Heliostats with a total area of 80,000 m2 are to be used to reflect solar radiation into a receiver. When the solar irradiation is 950 W/m2, steam is produced at 2 MPa and 400°C at a rate of 20 kg/s. This steam is expanded in a turbine to 20 kPa pressure. The enthalpy at the exit of the turbine is 2484.5 kJ/kg.(a) Determine the power output and the thermal efficiency of the plant when the solar radiation is 950 W/m2.(b) How much electricity can be produced per year if the average thermal efficiency is 15 % and the generator efficiency is 96 %? Question 2 To reduce cooling electricity consumption in an industrial plant, it is proposed to install an absorption refrigeration system running on solar energy. The absorption system costs $300,000 and the operating and maintenance expenses are $8000 per year.
