- A box is 50 cm high, and 30 cm wide and deep. It is filled with water. If there is a hole in the bottom that is 1 cm square, find the following: a) The speed of the water flowing through the hole at the bottom. b) The flow rate through the hole. C) How fast the water level at the top of the tub is dropping. For parts a and b, assume the water level at the top is constant. Does your result from part c make this assumption reasonable?what is the answer?A cube of side length 21.0 cm floats in oil. 18.0% of its volume is in water as shown. Use g = 10.0 m/s2. The density of the oil is 900 kg/m3. What is the density of the cube, in kg/m3?
- A large open tank contains water as shown in the figure. The level of the water in the tank is 8 m from the ground while the circular opening in the side of the tank is 1.5 m above the ground. If the discharge rate at the opening is 75 li/sec, determine the diameter of the opening. 1An incompressible fluid is flowing from left to right in the horizontal pipe shown. The diameter varies through this section of piping. At which of the points shown, labeled A through E, does the mass flow rate have greatest value? A O O O O O O с B B C The mass flow rate has the same value at all of the positions shown. A D EA length of clear plastic tubing is bent into a vertical U, as shown in the figure, and two liquids that do not mix are poured into it. Liquid A, with density ρA continues from the left column into the right. Its height is d1 in the left column and d2 in the right column. Liquid B, with density ρB, sits on top of liquid A in the right column. Its height is d3 above liquid A. Enter an expression for the density of liquid B, in terms of the other defined quantities.
