Question:
Ans: (a) 830 m/s, 0.951 kg/s (b) 38.8 kg/s
Transcribed Image Text:
9.15 (a) Steam enters a convergent-divergent nozzle with a velocity of 60 m/s, with a pressure 800 × 10° N/m² and with 79-6 K superheat. The steam leaves the exit section of the nozzle at a pressure of 160 x 103 N/m² with a dryness of 0-96. The cross-sectional area of the exit section is 12 cm?. The flow is adiabatic. Determine the steam velocity at the exit section and the steam mass flow rate. (b) The exhaust steam from the nozzle flows into a condenser and flows out as water at a temperature of 95 °C and negligible velocity. The cooling water enters the condenser at a temperature of 10 °C and leaves at a temperature of 25 °C; determine its mass flow rasé., 9.15 (a) Steam enters a convergent-divergent nozzle with a velocity of 60 m/s, with a pressure 800 × 10° N/m² and with 79-6 K superheat.
