7-142E Steam enters a diffuser at 20 psia and 240°F with a velocity of 900 ft/s and exits as saturated vapor at 240°F and 100 ft/s. The exit area of the diffuser is 1 ft2. Determine a) the mass flow rate of the steam and b) the rate of entropy generation during this process. Assume an ambient temperature of 77°F. | |
