Repeat Example 10-2, except calculate the diameter at the bottom of the column. For n-heptane: \(\mathrm{MW}=100.2\), bp \(98.4^{\circ} \mathrm{C}\), sp gravity \(=\) 0.684 , viscosity \(\left(98.4^{\circ} \mathrm{C}\right)=0.205 \mathrm{cP}, \sigma\left(98.4^{\circ} \mathrm{C}\right)=12.5\) dynes \(/ \mathrm{cm}\).
