7-45 Steam enters a steady-flow adiabatic nozzle with alow inlet velocity as a saturated vapor at 6 MPa and expands (a) Under the conditions that the exit velocity is to

be themaximum possible value, sketch the T-s diagram withrespect to the saturation lines for this process. (b) Determine the maximum exit velocity of the steam, in m/s. entropy change for the process as a function of the source tem-perature for final pressures of 250 kPa, 400 kPa, and 500 kPa,and discuss the results.
