Determine the nozzle outlet diameter in given Example required to increase the nozzle efficiency by decreasing the entropy production rate by 25.0%.
Example :
Determine the rate of entropy production as 0.2000 lbm/s of liquid water at 50.00°F, 95.00 psia flows through the nozzle on the end of a garden hose and exits at 14.70 psia. The inlet and outlet diameters of the nozzle are 1.000 and 0.2500 in., respectively.
Assume that the flow through the nozzle is too fast to allow a significant heat transfer to occur.
