$5.$ Complete problem $1-62$ from the textbook. Instead of plotting the height $,$ calculate the height $($h$)$ as a function of the diameter $($D$),$ and evaluate the height at the diameters listed in the problem.

$6.$Repeat problem $1-62$ from the textbook, but use liquid mercury as the fluid $.$ You'll need to look up appropriate values for the density$/$surface tension of liquid mercury.
