An empty water storage tank (cylindrical shape) with a diameter of 20 m and a height of 5 m is being filled at a rate of 2.5 m3/sec. However, it is also losing water (because of a hole in the bottom of the tank) at the rate of O = 0.7(h)0.6, where h is the depth of water in meters and O is the outflow rate in m3/sec. Determine the depth of water in the tank after 4 min. Use a depth interval of 1 m for the (2S/∆t + O) versus O relationship and a routing interval of 30 sec. What would the depth of water be in the tank if there was no leak?
