It is desired to siphon a volatile liquid out of a deep open tank. If the liquid has a vapor pressure of $200 \mathrm{mmHg}$ and a density of $45 \mathrm{lb}_{\mathrm{m}} / \mathrm{ft}^{3}$ and the surface of the liquid is $30 \mathrm{ft}$ below the top of the tank, is it possible to siphon the liquid? If so, what would the velocity be through a frictionless siphon, $1 / 2 \mathrm{in}$. in diameter, if the exit of the siphon tube is $3 \mathrm{ft}$ below the level in the tank?
