The enthalpies at the entry and exit of a nozzle are given then the velocities are

Question

If the enthalpies at the entry and exit of a nozzle are 3450 kJ/kg and 2500 kJ/kg and the initial

velocity is negligible then the velocity at the exit is

 (a) 806.2 m/s       (b) 25.5 m/s       (c) 36 m/s       (d) 1140.2 m/s
