I've already found T2 and A2 for part A. They are T2 = 310.2K and A2 = .0139m^2. But I can't figure out how to find the rate of entropy production with units KW/K (that's what my questions seems to be asking for, but it may be a typo). All of the solutions for this problem here on Bartelby find the rate of entropy production with units KW / (K*kg). Nitrogen (N₂) enters a well-insulated diffuser operating at steady state at 0.656 bar, 275 K with a velocity of 282 m/s. The inlet area is4.8 x 10-³ m². At the diffuser exit, the pressure is 0.9 bar and the velocity is 80 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.
