compressible flow:

A subsonic flow of air passes through a pipe of 2.5-cm diameter which is choked at the exit. At the pipe inlet, the stagnation pressure is 700 kPa and the stagnation temperature is 330 K. If f¯ = 0.022 and the pipe length is 12 m, what will be the mass flow rate through the pipe, in kg/sec?
