A set of 16 nozzles for an impulse turbine receives steam at 16 bar, 300°C. The pressure of steam at exit is 10 bar. If the total discharge is 245 kg/min and nozzle efficiency is 90%, find the cross-sectional area of the exit of each nozzle. If the steam has a velocity of 100 m/s at entry to the nozzles, find the percentage increase in discharge. [Ans. 1.256 cm²; 1.94%]

Read the question carefully and give me right solution with clear calculations.
![1. A set of 16 nozzles for an impulse turbine receives steam
at 16 bar, 300°C. The pressure of steam at exit is 10 bar.
If the total discharge is 245 kg/min and nozzle efficiency
is 90%, find the cross-sectional area of the exit of each
nozzle. If the steam has a velocity of 100 m/s at entry to
the nozzles, find the percentage increase in discharge.
