1. The problem statement, all variables and given/known data A storage reservoir is continuously filled through a pipe delivering 2.2cfs. The reservoir is circular in shape with a diameter of 20 ft. The height of the tank is 12ft. A pump operates for the last 5 minutes of successive 20 minute intervals, draining out 350 cubic feet of water. Determine the time it takes for the tank to overflow, assuming that it is initially empty. 2. Relevant equations v= delta x/ delta t 3. The attempt at a solution WOW! way too much information! i would try and figure the velocity, but the 350 cubic feet has no time association.
