Chapter 12, Problem 107P

Air enters a 5-cm-diameter, 4-m-long adiabatic duct with inlet conditions of ${\text{Ma}}_{\text{1}}=\text{ 2}.\text{8,}{T}_{\text{1}}=\text{ 38}0\text{ K}$ , and $P_{\text{1}}=\text{8}0\text{ kPa}$ . 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
