Two-bulb experiment for measuring gas diffusivitiesmanalytical solution (Fig. 18B.6) this experiment, described in Problem 18B.6, is analyzed there by a quasi-steady-state method. The method of separation of variables gives the exact solution s for the compositions in the two bulbs as in which γ_n is the nth root of γ tan γ = N, and N = SL/V. Here the + sign corresponds to the reservoirs attached at + L. Make a numerical comparison between Eq. 20D.l-1 and the experimental measurements of Andrew. Also compare Eq. 20D.l-1 with the simpler result in Eq. 18B.6-4.
