1. Steam enters a nozzle at 400°C and 800 kPa with a velocity of 10 m/s, and leaves at 300°C and 200 kPa while losing heat at a rate of 25 kW. For an inlet area of 800 cm?, determine the velocity and the volume flow rate of the steam at the nozzle exit. Determine the following: a. Velocity at the exit (m/s) b. Volume flow rate (m³/s) From steam table: h,=3267.7 kJ/kg h,=3072.1 kJ/kg 400°C 300°C 800 kPa Steam v,=0.39429 m /kg 200 kPa v,=1.3163 m /kg 10 m/s
