Q4) The nozzles receive steam at 1.75 MPa, 300 °C, and exit pressure of steam is 1.05
MPa. If there are 16 nozzles, find the cross-sectional area of the exit of each nozzle for a
total discharge to be 280 kg/min. Assume nozzle efficiency of 90%. If the steam has
velocity of 120 m/s at the entry to the nozzles, by how much would the discharge be
increased?
