A cylindrical storage tank has a radius of 1.43 m. When filled to a height of 3.75 m, it holds 13500 kg of a liquid industrial solvent. What is the density of the solvent?

An object made of iron appears 300 N lighter in water than in air. The density of iron is equal to 7870 kgm-3 , and the density of water is 1000 kgm-3 . a) What is the volume of the object? b) What is the object’s weight in air?

The two arms of a U-tube are not identical, one having 6 times the diameter of the other. A cork in the narrow arm requires a force of F1 = 79 N to remove it. The tube is filled with water and the wide arm is fitted with a piston with area A2. What is the minimum force, F2, that must be applied to the piston to push the cork out?

A container has a large cylindrical lower part with a long thin cylindrical neck open at the top. The lower part of the container holds 19.5 m3 of water and the surface area of the bottom of the container is 7.80 m2. The height of the lower part of the container is 2.50 m, and the neck contains a column of water 8.50 m high. The total volume of the column of water in the neck is 0.200 m3. What is the magnitude of the force exerted by the water on the bottom of the container? in MN

A hollow spherical iron shell floats almost completely submerged in water. The outer diameter is 60.5 cm, and the density of iron is 7.87 g/cm°. Find the inner diameter. Number i Units

To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She finds that the specimen weighs twice as much in air as it does in water. The density of the solid part of the specimen is 6.22 × 10³ kg/m³. What fraction of the specimen's apparent volume is solid? Number i Units

An​ outdoor, rectangular pool on campus is 4.5 meters​ [m] in width and 7.5 meters​ [m] in length. You may assume the depth of the pool is constant. If the pool is filled with pure​ water, the total pressure probe at the bottom of the pool reads 16.5 ​pound-force per square inch​ [psi]. What is the volume of the water in the pool in units of kiloliters​ [kL]?     Length Force Mass Pressure 1 ft=12 in 1 N=0.225 lbf 1 kg=2.205 lbm 1 atm=101325 Pa 1 in=2.54 cm   1 slug​ = 14.5939 kg 1 atm=14.7 psi 1 m=3.28 ft   Density of water=1000 ​kg/m3 Surface pressure=1 atm

Heptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder with an inside diameter of  3.42  cm contains 37.7  g of heptane and 30.3 g of water. What is the combined height of the two liquid layers in the cylinder?  The volume of a cylinder is π r2h, where r is the radius and h is the height.

A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead, the pipe's diameter is 53.5 cm and the flow speed of the petroleum is 13.1 m/s. At the refinery, the petroleum flows at 5.25 m/s. What is the volume flow rate of the petroleum along the pipe, and what is the pipe's diameter at the refinery? volume flow rate: m³/s diameter: cm

A hollow spherical iron shell floats almost completely submerged in water. The outer diameter is 66.1 cm, and the density of iron is 7.87 g/cm³. Find the inner diameter. Number Units
