Problem 6.070 si nitrogen (n2) enters a well-insulated diffuser operating at steady state at 0.656 bar, 300 k with a velocity of 282 m/s. the inlet area is 4.8 x 10-3 m2. at the diffuser exit, the pressure is 0.9 bar and the velocity is 140 m/s. the nitrogen behaves as an ideal gas with k = 1.4. (a) determine the exit temperature, in k, and the exit area, in m2. (b) for a control volume enclosing the diffuser, determine the rate of entropy production, in kw/k.
