1. An ideal gas flows in steady state adiabatic flow along a horizontal pipe of inside diameter di, = 0.02 m. The pressure and density at a point are P = 20000 Pa and r = 200 kg/m3 respectively. He density drops from 200kg/m3 to 100kg/m³ in a 5m length. Calculate the mass flux assuming that the Fanning friction factor f = 9.0 x 10^-3 and the ratio of heat capacities at constant pressure and constant volume = 1.40.
