EXPERIMENT: BUOYANCY (The objective of the experiment is to design and build a boat with the greatest buoyant force)   

Make an CONCLUSION

Question Basis:

1) Did you ever wonder how aircraft carriers and cruise ships are able to carry so much weight and float over the ocean?

2) Show how buoyancy equations are derived for floating and submerged bodies. Discuss its significance in the civil engineering profession if there are any.....

 

Answer:

1. Steel ships are denser than water. Aircraft carriers and cruise ships are composed of very large steel vessels. The ships and carriers float in the water because of their shape and its parts. The entire cruise ships are not made of solid steel yet the outer part is a hollowed-out shells of steel. So that, there is air in the interior of the ship. Where air is less dense than water that is why it floats above the water. The density of water is greater than the average density of the total volume of cruise ships including the components. As it is floating in the water, the weight is equal to the displaced fluid. On the other hand, if the density of water is less than the total average density of the ship, the cruise ship will sink below the surface of the water. If the water enters the cruise ship, the average density of the ship become more larger than the density of the water.

2. The derivation of buoyancy equation is shown in figure 1. The equation is given by:

                       F_b = F₂ - F₁

F₁ = P₁ A = h₁ p g A

F_{2 =} P₂ A = h₂ p g A

where:

             F_b = buoyant force

              P = Pressure

              A = area where pressure acts

              h = distance of object to the surface of the fluid

              p = density of fluid

              g  = gravitational constant

Buoyancy is very important in civil engineering profession because it is one factor that is considered in designing an underground concrete structure. Buoyant force that is produced by fluid is required to prevent the concrete structure from floating upward. 

Step-by-step explanation

1. This explains the Archimedes' Principle also known as Buoyancy. Archimedes Principle states that "When a stationary body is completely submerged in a fluid, or floating so that it is only partially submerged, the resultant fluid force acting on the body is called the BUOYANT FORCE. This force is equal to the weight of the fluid displaced."
