A solar concentrating heat exchanger system directs sunlight onto a long straight pipe. The pipe receives heat from sunlight at the rate of 153.616 Btu/hr per foot of length. Water enters the pipe at 50 lbm/hr as saturated liquid at 300 degrees F and is heated isothermally; it leaves as superheated vapor at 20.0 psia. Suppose steady state, steady flow conditions. Please show your work.
a) Decide the length of the pipe needed to achieve the desired conditions
b) Decide the rate of entropy production in this solar concentrator.
c) Demonstrate whether this system violates the second law of thermodynamic
