✦ Synopsis

The determination of the partial coefficient of heat transfer from air to a drying fluidized mass of silicagel is given. The data obtained can be correlated by means of the equation h = 1.32 (R)"'re. A comparison of the external and internal heat exchange in a fluidized mass is presented.
