Nitrogen, can can be assumed to behave as an ideal gas flows through a rectangular duct with a cross-sectional area of 0.01m2. at the inlet, the gas has a velocity of 1m/s, a temperature of 30 c, and a pressure of 100kpa. there is a slight pressure drop across the length of the duct to 90kpa find the following (a mass flow rate [kg/s] at the exit (if you cannot, explain) (b volumetric flow rate [m3/s] at the exit
