$13-3.$ Begley has reported temperature data taken in a bed consisting of $\frac{1}{4}\frac{1}{4}-$in$.$ alumina pellets packed in a $2-$in$.$ pipe $($actual $2\mathrm{.}06$ in$.$ ID$)$ through which heated air was passed. The tube was jacketed with boiling glycol to maintain the tube wall at about $197C.$ For a superficial mass velocity $($average$)$ of air equal to $300l\frac{b}{hr}(f{t}^2)$ the experimental temperatures at various packed$-$bed depths are as follows:
