A mixture of He and N2 gas is contained in a pipe at 298 K and 1 atm total pressure which is constant throughout. At one end of pipe at point 1 the partial pressure pA1 of He is 0.60 atm and at the other end 0.2m pA2 = 0.20 atm. Calculate the flux of He at steady state, if DAB of He-N2 mixture is 0.687 x 10-4 m2/s. Answer: JA= 5.63 x 10-6 kgmol / sm2

Principal Quantities and EOS

A physical quantity represents the physical state of a system. It is expressed as the product of a number and unit. The basic quantities used in science are length, mass, and time. The principal quantities are the quantities that are independent of other quantities.
