Air flows down a pipe with a diameter of 0.15 m. At the inlet to
the pipe, the Mach number is 0.1, the pressure is 70 kPa, and the
temperature is 35°C. If the flow can be assumed to be adiabatic and
if the mean friction factor is 0.005, determine the length of the
pipe if the Mach number at the exit is 0.6. Also, find the pressure
and temperature at the exit to the pipe.
