# Air enters a 5-cm-diameter, 4-m-long adiabatic duct with inlet conditions of Ma 1 = 2.8, T 1

## Question:

Air enters a 5-cm-diameter, 4-m-long adiabatic duct with inlet conditions of Ma_{1} = 2.8, T_{1} = 380 K, and P_{1} = 80 kPa. It is observed that a normal shock occurs at a location 3 m from the inlet. Taking the average friction factor to be 0.007, determine the velocity, temperature, and pressure at the duct exit.
