G (Problem 13.5). A 300 ft-long 6-ft-wide parabolic trough concentrator receives normal sun radiation at 905 W/m2. A pipe at the focal line received 450 lbm /hour of water at 200 psia and at 100 oF and exits at 180 psia. Calculate the pipe exit conditions. Assume the concentrator reflective losses of 5 percent.
