A concentrating solar power (CSP) plant is planned for a site about 40 miles due south of Albuquerque, NM and about 10 miles east of the town of Belen, NM. The plant will operate with a steam power cycle with a low temperature of 50C, a boiler pressure of 80 bar, and a superheat maximum temperature of 350C. Use NREL’s "Solar Prospector" for solar resource evaluation. What is the approximate total solar concentrator aperture area required to achieve an 80 MW output for the power plant? (note: aperture area = solar concentrator projected area = width (aperture) x length of collector)

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
