Extracted text: Problem 1 The diffusion coefficient DAB for the interdiffusion of two gases A and B may be estimated using the following empirical relationship: T2/3 1 DAB = 0.043 MAMB P(v + where DAB = diffusion coefficient cm?/s MA, MB = molecular weights of A and B, respectively P = total pressure, atm VA, Vg = molecular volumes of A and B, respectively Find the value of the constant corresponding to 0.0043 for an empirical formula DAB in ft2/h and use P in psi and T in °R.
