Question: Consider a one-dimensional isentropic flow through a duct. At a certain section of this duct, the velocity is 360 m/s, the temperature is 45°C, and the pressure is 120 kPa. Find the Mach number and the stagnation temperature and pressure at this point in the flow. If the temperature at some other point in the flow is 90°C, find the Mach number and pressure at this point in the flow.
