Question

CO gas flows steadily through a varying cross-sectional area duct (nozzle) with mass flow rate of 3 Kg/s. The CO enters the duct at a pressure of 1400 kPa and 200 °C with a low velocity and it expands in the nozzle to a pressure
of 200 kPa. The nozzle is designed so that the flow can be approximated as isentropic. Determine the density, velocity, flow area and Mach number at exit. Take Cp = 0.846 kJ/kg K, R= 0.1889 kJ/Kg K and γ=1.289.
