The exit of a constant area duct has a volume flow rate of 1000 m3/min of air at astatic temperature and pressure of 293 K, and 150 kPa, respectively. The area ofthe duct is constant along the length, the diameter is 0.3 m, and the length is 50 m. The friction factor is 0.005. The flow is adiabatic. Determine the Mach numberat the exit, the inlet static pressure, the inlet static temperature, and the change inentropy s2-s1.
