(b) Steam at 4 MPa and 400 °C enters a nozzle steadily with a velocity of 60 m/s, and it leaves at 2 MPa and ii. iii. iv. V. i. 300 °C. The inlet area of the nozzle is 50 cm², and heat is being lost at the rate of 75 kW. Write the energy balance equation for this process. The mass flow rate of the steam, kg/s. The outlet velocity of the steam, m/s. The outlet area of the nozzle, m². Calculate the velocity of the steam at the outlet if the inlet and outlet pressure, temperature, and mass flow rate are the same, but the nozzle is well insulated (adiabatic process), m/s.
