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.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
