Find mass flow rate of steam and rate of entropy generation
Steam enters a diffuser at 20 psia and 240oF with a velocity of 900 ft/s and exits as saturated vapor at 240oF and 100 ft/s. The exit area of the diffuser is 1 ft2. Determine (a) the mass flow rate of steam and (b) the rate of entropy generation.
