Steam enters a 100-mm-inner-diameter pipe at 760 K and 4.0 MPa. The steam cools as it travels through the pipe and exits at 4 MPa with a quality of 0.93. The average velocity of the fluid exiting the pipe is 25 m/s. Show the entering and exit states on a T–v diagram. Before you perform any numerical calculations, consider whether you expect the velocity at the entrance to be greater than, less than, or the same as the exit velocity. Determine the average velocity of the steam at the pipe entrance.
