EXAMPLE 17-3 Gas Flow through a Converging-Diverging Duct Carbon dioxide flows steadily through a varying cross-sectional area duct such as a nozzle shown in Fig. 17-12 at a mass flow rate of $$3.00\mathrm{kg}/\mathrm{s}$$. The carbon dioxide enters the duct at a pressure of $$1400\mathrm{kPa}$$ and $$200^{?}\mathrm{C}$$ with a low velocity, and it expands in the nozzle to an exit pressure of $$200\mathrm{kPa}$$. The duct is designed so that the flow can be approximated as isentropic. Determine the density, velocity, flow area, and Mach number at each location along the duct that corresponds to an overall pressure drop of $$200\mathrm{kPa}$$. SOLUTION Carbon dioxide enters a varying cross-sectional area duct at specified conditions. The flow properties are to be determined along the duct.
