Question

Water in steady flow enters a pipe at 5 MPa and 5^oC where it is heated in a constant pressure process to 1000^oC. The inlet velocity is 5 m/s, and the inlet flow area is 0.005 m². The exit flow area is 0.007 m2. (Hint: you may need to approx. h in the sub cooled region)

a. Calculate the mass flow rate at the inlet and exit

b. Calculate the exit velocity

c. Calculate the rate of heat transfer in MW.
