Water (density p-1000 is discharging from through a hole at the bottom of a graduated 71 cylinder. The mass flow rate exiting the container may be approximated by: Where Cd is the dimensionless discharge coefficient, A, is the area of the discharge hole, g is the acceleration due to gravity, and y is the water height in the container. The diameter of the graduated cylinder is 8 cm.

For the following givens, use matlab or a spreadsheet to estimate the time to empty half the water from the container.

For partial credit, perform a simple calculation to estimate an amount of time known to be too short but greater than zero.
