Thermodynamic Steam

 Water flows through the tubes of a boiler. The water enters a tube of diameter 0.13m under pressure 7 MPa and temperature 65C and leaves the tube as superheated steam (6 MPa, 450C). If the outlet velocity of the steam is 80m/s, calculate the velocity and volume flow rate at the inlet.
