Steam at 500°C and 10.0 MPa flows into a turbine through a circular duct of 5.0 cm diameter. The volumetric flow rate of the steam is 8.0 m3/s. Determine the vel°City and the mass flow rate of the steam entering the turbine.
Given: T = 500°C; P = 10.0 MPa; D = 5.0 cm = 0.05 m; V? = 8.0 m3/s What will be an ideal response?
