The axis of the conical take is perpendicular to the horizontal surface of ground. The height of the tank is 3 m. The tank is completely filled with water, and the volume of the water is 27 L. There are three outlet taps, one at the bottom, second at a height of 1 m, and the third at a height of 2 m. The rate of outflow of each of the three taps is 1 L/min. If all the three taps are opened simultaneously at 12 noon, at what approximate time will the tank get completely empty?
