Liquid‐phase Peclet numbers have been measured for 1/4 in. Raschig rings with countercurrent air flow in a 2 in I.D. column. The response curve has been analyzed by a computer program, since the output data was collected directly on paper tape. The Peclet number calculated from a moments analysis is considered unreliable, and the diffusion model can be rejected for the liquid phase. If the Peclet number is calculated by a least‐squares fit, and if the result is forced through the peak in the response curve, then a correlation for over one hundred runs with gas flows from 0 to 99% of flooding is given by Equations (7) and (8).
