A solar concentrating heat exchanger system directs sunlight onto a long,straight pipe. The pipe recieves 153.616 btu/h per foot of length. If water enters the pipe @ 300 f and is heated isothermally so that it leaves as vapor @ 20 psia then:
A. How long is the pipe for steady state,steady flow conditions.
B. What is the entropy production.
C. Show whether this system violates the second law of thermodynamics
