Air enters a 27-m long 5-cm diameter adiabatic duct at a velocity of 85 m/s, static temperature of 450 k and a static pressure of 220 kpa. the average friction factor (4) for the duct is estimated to be 0.023. determine: (i)- mach number at the exit. (ii)the mass flow rate of air.(iii) what is the length that needs to be added (or subtracted) for the flow to reach sonic conditions at the exit?
