The flask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet.  You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t).

Questions:
1. So, I would like to escape from the shackles at the exact instant that the
water reaches the top of my head. I need your help in determining how tall
the stool should be?
2. So at any time after the water begins flowing, I want to know how high the
water is in the tank? how fast the water is rising?
3. I would like to know how long I will have to hold my breath during the last
part of the stunt.
