Question Four Air enters a pipe at a Mach number of 2.5, a temperature of 400 °C and a pressure of 70 kPa. The pipe has a diameter of 2.0 cm and the flow can be assumed to be adiabatic. A shock occurs in the pipe at a location where the Mach number is 2. If the Mach number at the exit from the pipe is 0.8 and if the average friction factor is 0.005. Find the distance of the shock from the entrance to the pipe and the total length of the pipe. Also, find the pressure at the exit of the pipe.

Question Four
Air enters a pipe at a Mach number of 2.5, a temperature of 400 °C and a pressure of 70 kPa. The
pipe has a diameter of 2.0 cm and the flow can be assumed to be adiabatic. A shock occurs in the
pipe at a location where the Mach number is 2. If the Mach number at the exit from the pipe is 0.8
and if the average friction factor is 0.005. Find the distance of the shock from the entrance to the
pipe and the total length of the pipe. Also, find the pressure at the exit of the pipe.
