How fast does a tank drain? Of course this depends on the shape of the tank and is governed by a physical principle known as Torricelli's law. This note investigates some connections between tank shape and a mathematical function related to the time required for the tank to drain completely. The techniques employed provide some interesting illustrations of the fundamental theorem of calculus, l'Hopital's rule and the mean value theorem for integrals.
