What is the unit of diffusion flux “J” in the Fick’s law equation?
In a gas mixture of hydrogen and oxygen, steady state equimolar counter diffusion is occurring at a total pressure of 100 kPa and temperature of 20°C. If the partial pressures of oxygen at two planes 0.01 m apart, and perpendicular to the direction of diffusion are 15 kPa and 5 kPa, respectively and the mass diffusion flux of oxygen in the mixture is 1.6 * 10–5 kmol/m2.sec, calculate the molecular diffusivity for the system.For equimolar counter current diffusion:
Refer to Q6, and calculate the partial pressure at a point 0.02 m apart from point 1.
Methane diffuses at steady state through a tube containing helium. At point 1 the partial pressure of methane is pA1 = 55 kPa and at point 2, 0.03 m apart PA2 = 15 KPa. The total pressure is 101.32 kPa, and the temperature is 298 K. At this pressure and temperature, the value of diffusivity is 6.75 * 10–5 m2/sec.Calculate the flux of CH4 at steady state for equimolar counter diffusion.For steady state equimolar counter diffusion, molar flux is given by:
