An open cylindrical tank 5 m in diameter and 6 m high is full of water. Two orifices are placed on the vertical side of the tank. One orifice is at elevation 22.50 m and the other at 20.50m elevation. The area of each orifice is 0.002 m^2. Use Cc = 0.62 and Cv = 0.98. The bottom of the tank is at elevation 20 m. a) How far from the vertical side of the tank will the jets of water intersect at an instant when the tank is full? b) What is the elevation where the jets intersect? c) What is the time that it will take to lower the water level by 1.20 m?

A solid sphere of diameter 1m and average density of 780 kg/m3 is completely submerged in a tank filled with water. It is held in place by a string attached to the bottom of the tank, as shown. The mass distribution inside the sphere is non uniform, so the center of mass lies at a distance 0.50R from the geometric center. Suppose that the sphere is attached rigidly to a massless horizontal rod of length 0..75 m and negligible volume oriented along the line formed by the center of mass and the geometric center of sphere as shown. The rod is attahced on the side of the sphere nearer the center of mass, and the far end of the rod is attached to the fixed pivot. What is the buoyant force acting on the sphere?
