In a laboratory experiment, a small, horizontal cylindrical tank is filled with water to a height of 2 meters. The tank has a diameter of 0.5 meters. A small opening at the bottom of the tank allows water to flow out. According to Torricelli’s theorem, the speed of efflux of a liquid under the force of gravity through an orifice is proportional to the square root of the height of the liquid column above the orifice. If the height of the water in the tank decreases to 1 meter, what will be the new speed of the water exiting the opening?
