A reservoir of glycerin has a mass of 1200 kg and a volume of 0.952 m². Find the glycerin's weight (W), mass density (0), specific weight (8),and specific gravity (s.g.)

3. Two immiscible liquids A and B are in a container. A 100-g object is dropped onto the container and the object is observed to be at the liquid-liquid interface with 47% of the object's volume in A and 53% in B. If the density of the object is 7.6 g/cm³, what are the densities of A and B.

A ship displaces 4000 cubic feet of sea water. Find the volume of water that the ship will displace in fresh water

An easy experiment to estimate the density of a body is to weigh it in air and water. Consider a body of unknown density and volume. You weighed it in air, finding a value of 100 N. Then, using a special scale imported from the United States, you weighed the object submerged in water, finding a value of 5.6 lbf. Based on these results, find the density and volume of the object. Remember that the scale measures the result of the balance of forces on the body (or the sum of the forces). Show this balance of forces (or force diagram) on the body during your solving. Express the result in units of the International System and the American System of Engineering, and show any unit conversion calculations using the conversion factor. Consider the densities of water and air equal to 1000 kg/m3 and 1.18 kg/m3, respectively.

Suppose there is a triangle-shaped window installed vertically on the side of a city under the ocean. Assume that the bottom of the triangle is 2,000 ft below the surface of the water. The density of sea water is 63.93 pounds per cubic foot. The top of the triangle is 10 ft wide, and the triangle is 5 feet tall and is symmetrical about its middle. Refer to the drawing below: Find the fluid force on the window due to the ocean. 10 5

An aquarium 7ft long, 3ft wide, and 5ft deep is full of water. The gravitational acceleration is g = 32ft/s². The density of water is p = 1.95slug/ft³. Answer the following questions. 1.
