Fluid is flowing through a pipe at a rate of 100 gal/min. The inlet pressure is 20 psig and the outlet pressure is 0 psig. The pipe is submerged in a lake that maintains the fluid at a constant temperature of 50(F). At what rate (Btu/h) is heat dissipated from the pipe? At what rate [Btu/(hR)] is entropy generated?
Two mirrors meet at a 127° angle. If light rays strike one mirror at 40° as shown, at what angle ? do they leave the second mirror.
