Consider the nozzle in Problem 9.112. What is the second law efficiency for the nozzle?
A nozzle in a high pressure liquid water sprayer has an area of 0.5 cm2. It receives water at 250 kPa, 20°C and the exit pressure is 100 kPa. Neglect the inlet kinetic energy and assume a nozzle isentropic efficiency of 85%. Find the ideal nozzle exit velocity and the actual nozzle mass flow rate.
