3. Two vertical cylindrical tanks A and B having radius of 1.5m and 2m, respectively, are connected with a 215mm diameter tube at its lower portion and having coefficient of discharge equal to 0.63. When the tube is closed, the water surface of tank B to tank A is 4.7m. How long will it take in minutes after opening the tube, for the water surface in tank A to fall by 1.75m? 4. An open cylindrical tank 2m in radius and 10m high contains 6m of water and 4m of seawater. Find the time in minutes to empty the tank through a 150mm diameter orifice at the bottom. Assume coefficient of
