Air with a mass flow rate of 5 kg/s enters a horizontal nozzle operating at steady state at 450 K, 350 kPa, and velocity of 3 m/s. The nozzle is well insulated. At the exit, pressure is 300 kPa and temperature is 390 K. Using the ideal gas model for air, the area at the inlet is m², and the velocity at the outlet is Are potential effects negligible? Why? m/s. Is heat transfer negligible? Why? Note that you may choose to model the specific heat as constant.
