An adiabatic control volume with steam as the working fluid operates at steady flow conditions, with the inlet state of 4000 kPa, 300°C, with a velocity of 40m/s. The exit pressure and temperature are 400 kPa and 200°C, respectively. The mass flow rate is 4kg/s.
Determine:
a) The exit velocity (449 m/s)
b) The inlet and exit areas (59 cm2, 48 cm2)
