A cylindrical tank of water is 20 m in diameter and 3.5 m tall. There is a 1.0 cm diameter hole at the bottom from which water is leaking. A feeder pipe at the top of the tank, 4.0 m above the ground delivers water at a rate of 0.02 m/min. Ir the tank is initially half full, tal what is the water flow rate in m^3/sec from the top feeder pipe? (bi what is the pressure at the bottom of the tank? (Hint: Bernoul's principle) () what is the water speed at the bottom? (d) what is the leaking flow rate at the bottom? fe) at what rate is the volume of water changing? (Assume the tank is open to air at the top)
