A tank filled with water has two taps to exhaust and pour. A hollow sperical ball is half submerged in water. Through one tap, water is taken out and through another tap, a liquid of density double the density of water is poured in tank such that volume of liquid in tank remains constant. Sphere will

The figure shows the commonly observed decrease in diameter of a water stream as it falls from a tap. The tap has internal diameter D_(0) and is connected toa large tank of water. The surface of the water is at a height b above the end of the tap. By considering the dynamics of a thin "cylinder" of water in the steam answer the following: (ignore any reistance to the flow and any effects of surface tansion, given rho_(w) = density of water) The equation for the water speed v as a funcation of the distance x below the tap will be:

By considering the dynamics of a thin "cylinder" of water in the steam answer the following: (ignore any reistance to the flow and any effects of surface tansion, given rho_(w) = density of water) A student observes after setting up this experiment that for a tap with D_(0) = 1 cm at x = 0.3 m the stream diameter D = 0.9 cm . The heights b of the water above the tap in this case will be:

Water is poured into an empty cylindrical tank at a constant rate. In 10 minutes, the height of the water increased by 7 feet. The radius of the tank is 10 feet. What is the rate at which the water is poured?
