Consider the adiabatic flow of air through a pipe of 0.2-ft inside diameter and 3-ft length. The inlet flow conditions are M1 = 2.5, p1 = 0.5 atm, and T1 = 520°R. Assuming the local friction coefficient equals a constant of 0.005, calculate the following flow conditions at the exit: M2, p2, T2, and po2 .
