    100 m/s. The inlet area of the diffuser is 14 cm . The system loses heat at the rate of 25 kJ/s

    to the surroundings. Neglect changes in potential energy between the inlet and outlet.

    1. What is the mass flow rate of the water vapor, in kg/s?

    2. What is the specific enthalpy of superheated steam leaving the diffuser, in kJ/kg?

    3. Estimate the temperature of the superheated steam at the outlet, in °C.

      (No linear interpolation, just give the nearest temperature value).
