Steam at a pressure of 10 bar and 95% dry is supplied through a convergent-divergent nozzle to the wheel chamber where the pressure is maintained at 0.12 bar. The mass flow rate through the nozzle is 8.16 kg/kWh and the work developed by the wheel is 110 kW. Determine the following: ????Pressure of the throat for maximum discharge ????Number of nozzles required if throat diameter of each nozzle is 5 mm ????The exit diameter of nozzle if 10% of overall enthalpy drop overcomes friction in the divergent portion 5. Steam at a pressure of 10 bar and \( 95 \% \) dry is supplied through a convergent-divergent nozzle to the wheel chamber where the pressure is maintained at 0.12 bar. The mass flow rate through the nozzle is \( 8.16 \mathrm{~kg} / \mathrm{kWh} \) and the work developed by the wheel is 110 kW . Determine the following: (a) Pressure of the throat for maximum discharge (b) Number of nozzles required if throat diameter of each nozzle is 5 mm (c) The exit diameter of nozzle if \( 10 \% \) of overall enthalpy drop overcomes friction in the divergent portion
