Question: Consider compressible flow through a long, well-insulated duct. At the inlet to the duct the Mach number, pressure, and temperature are 0.3, 100 kPa, and 30°C respectively. Assuming that the flow is adiabatic and that the pipe is sufficiently long to ensure that the flow is choked at the exit, find the velocity and temperature at the pipe exit.
