Calculate a test data of this algortihm

The owners of a mall need to know when a parking lot will flood based on the rate rainfall. This lot is has one sewer drain. Develop a process that will take the ask the user the size of the lot in square feet, the rain fall in inches per hour, the flow rate of the sewer in feet per second, and the cross section of the sewer pipe in square feet. When the amount of water accumulating by the rain is greater than the amount that can be removed by the drain output a message that the lot should be evacuated, otherwise output a message that the cars are safe.
