In his experiment to test whether the crown of the King of Syracuse was made of pure gold or not, Archimedes immersed the crown into a container filled with water. He noted that the crown displaced 150 mL of water. If the mass of the crown is 2675 g, is it made of pure gold?
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

When immersed in a container filled with water, a ball of mass 500 g displaced 250 mL of water. How much water would a 350 g ball (made of the same material as the 500 g ball) displace?
A storage tank that is 15 m high is open at the top and initially filled with water. It developed a hole 12 m below the surface of water along its side. (a) What is the initial speed of water through the hole? (b) How far from the base of the tank will the water stream strike the ground?
A party balloon with a radius of 12.5 cm is filled with helium. How much weight can this balloon lift? Neglect the weight of an empty balloon. (density of air = 1.29 kg/m3, density of helium = 0.178 kg/m3)
A narrow stream of water squirts out of a hole at the side of an open tube and lands on the ground 1.75 m from the base of the tube. The hole is 12.5 m above the base of the tube. (a) What is the speed of water leaving the hole? (b) How deep is the hole?
