Air enters a 2.953 inches inner diameter (ID) pipe at a velocity of 60 m/s at 27 C and 177318.75 Pa pressure. At the exit point, the air flows through a 1.969 inches ID pipe at 60 C and 136788.75 Pa. What is the mass flux and the volumetric flow rate of the gas at the exit point? (Assume that air is an ideal gas with MW=28.97 g/mol. Gas constant R00.0821 L.atm/molK)
