According to Torricelli€™s theorem, the velocity of a fluid draining from a hole in a tank is V ≈ (2gh) 1/2, where h is the depth of water above the hole, as in Fig. P3.28. Let the hole has area Ao and the cylindrical tank have bottom area Ab. Derive a formula for the time to drain the tank from an initial depth ho.
