Water flows through the tubes of a boiler. The water enters a tube of diameter 0.13m under pressure 7 MPa and temperature 65°C and leaves the tube as superheated steam (6 MPa, 450°C). If the outlet velocity of the steam is 80m/s, calculate the velocity and volume flow rate at the inlet. 7 MPa Steam 6 MPа, 450°C 65°C 80 m/s Hints: From the property tables find the specific volume of water and superheated stream at given conditions. What is the mass flow rate at the outlet? Is it the same as at the inlet? What is the relation between the volumetric flow rate and flow velocity?
