In an isentropic nozzle, operating at steady state, the specific flow energy (j) and specific entropy (s) remain constant along the flow. The following properties are known at the inlet and exit ports of an isentropic nozzle discharging water at a steady rate of 2 kg/s. Inlet: p1 = 300 kPa, A1 = 4 cm2; Exit: p2 = 100 kPa. Determine
(a) The exit velocity (V2).
(b) The exit area. Use the SL model for liquid water.
(c) What-if Scenario: What would the exit velocity be if the inlet kinetic energy were neglected?
