Question: A gas with a molar mass of 4 and a specific heat ratio of 1.67 flows through a variable area duct. At some point in the flow, the velocity is 200 m/s and the temperature is 10°C. Find the Mach number at this point in the flow. At some other point in the flow the temperature is -10°C. Find the velocity and Mach number at this point in the flow assuming that the flow is isentropic.
