with the data derived from various sources as the analysis of [I] was tested for a wide range of variables.
Thus, the significant conclusions that can be made out of the present note is that the non-dimensional film thickness (8' >5) for co-current liquid films both for laminar and turbulent flow conditions can be evaluated loo-from a single universal relationship given in Eq. 9.

The paper describes two distinctive forma of thermal instability which can make their 8pp93u8nce in gas-solid reactions. The llrst is due to an unstable type of crossing of the curven which repreeent the rate of heat genemtion by reaction within the solid and the rate of heat loss from its surface.
main reason for the deviation in this system is ascribed to the polar nature and the heterogeneity of the adsorbent which results in nonideal interactions among the adsorbate molecules through adsorbent-adsorbate interaction.
