The distribution of residence-times of the gas flowing through a fluidised catalyst regenerator has been determined by using helium as a tracer. Only about 5 y0 of the gas spends less than half, and about 5 y0 more than twice, the mean residence-time in the regenerator. It appears that the flow thro

Tue residence time distribution for an ideal fluid in a cylindrical vessel with diametrically opposed line source and sink has been obtained by WOOD [l]. The present note shows the derivation of an expression to obtain residence time distribution for the same vessel with a line source and sink in an

The equation for the calculation of mean residence time of drug in plasma, t(p), is obtained. It is shown that the previously suggested calculation of t(p) considerably overestimates the true value in most cases. It is suggested that due to the possible initial (before establishing the uniform drug
Abstiact-A theoretical treatment of heat or mass transfer in particulate systems is made with emphasis on the effect of particle size and residence time distribution functions on average and total transfer rates. Two differential equations (one for each phase) for mass or heat transfer are solved si
