A gas of CH4 and He is contained in a tube at 101.32 kPa pressure and 298 K. At point the partial pressure of methane is pA1 = 60.72 kPa at a point 0.02 m distance away pA2 = 20.26 kPa. If the total pressure is constant through the tube, calculate the flux of CH4 (methane) at steady state for equimolar counter diffusion. Answer: JA = 5.52 x 10-5 kgmol / sm2

Units and Dimensions

Dimensions are the basic concepts of the measurement of quantities. Units are the means of expressing the dimensions. For instance, an area has a dimension of L2 and a unit of m2.
