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.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
