Agas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure. calculate the pressure required to maintain this rate of flow under isothermal conditions. the volume occupied by 1 kmol at 273 k and 101.3 kn/m2 is 22.4 m3.
