Water at 120 F and 60 psia flows through a ½" diameter pipe at 0.6 lbm/s and is steadily mixed with 0.2 lbm/s water at 60 F and 60 psia from a ½" diameter pipe. The mixed water stream leaves through a shower head and is collected in a tub before flowing down the drain. The surroundings are at 70 F.
a.Find the flow availability for the hot and cold streams and for the collected pool in the tub.
b.Find the exergy destruction for the process.
c.How much does the velocity contribute?
d.Suggest ways to decrease the exergy destruction in this process
