    Suppose a conical tank (think of an ice cream cone, point down) has a capacity of 7 gallons, and that 3 gallons of water are in it already. Water is added at a rate of 6 gallons per minute, but the cone springs a leak near its tip after 10 seconds. Water exits the tank at a rate determined by Torricelli's Law, v2gh (where v is the linear velocity of the water, g the acceleration due to gravity, and h...

    A conical tank of radius R and height H, pointed end down, is full of water. A small hole of radius r is opened at the bottom of the tank, with r, much much less than, R so that the tank drains slowly. Find an expression for the time T it takes to drain the tank completely. Hint 1: use Bernoulli’s equation to relate the flow speed from the hole to the height of the water in the cone. Hint...
