What is Fluid Mechanics?

Fluid dynamics is “the branch of applied science that is concerned with the movement of liquids and gases”. It involves a wide range of applications such as calculating force & moments, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space, and modelling fission weapon detonation.

What Is a Buoyant Force?

The buoyant force is the upward force exerted on an object wholly or partly immersed in a fluid. This upward force is also called Upthrust. Due to the buoyant force, a body submerged partially or fully in a fluid appears to lose its weight, i.e. appears to be lighter. The following factors affect buoyant force: the density of the fluid, the volume of the fluid displaced, the local acceleration due to gravity. An object whose density is greater than that of the fluid in which it is submerged tends to sink. If the object is either less dense than the liquid or is shaped appropriately (as in a boat), the force can keep the object afloat. In terms of relative density, if the relative density is less than one, it floats in water and substances with a relative density greater than one sink in water.

How to Calculate Buoyant Force given Bottom and Top Force?

Buoyant Force given Bottom and Top Force calculator uses Buoyant Force = Bottom Force-Top Force to calculate the Buoyant Force, The Buoyant Force given Bottom and Top Force formula is defined as the difference between Net downward force and net upward force. It is a common experience that an object feels lighter and weighs less in a liquid than it does in air. This can be demonstrated easily by weighing a heavy object in water by a waterproof spring scale. Also, objects made of wood or other light materials float on water. These and other observations suggest that a fluid exerts an upward force on a body immersed in it. This force that tends to lift the body is called the buoyant force. The buoyant force is caused by the increase of pressure with depth in a fluid. Thus, we conclude that the buoyant force acting on the plate is equal to the weight of the liquid displaced by the plate. For a fluid with constant density, the buoyant force is independent of the distance of the body from the free surface. It is also independent of the density of the solid body. Buoyant Force is denoted by Fbuoyant symbol.

How to calculate Buoyant Force given Bottom and Top Force using this online calculator? To use this online calculator for Buoyant Force given Bottom and Top Force, enter Bottom Force (FBottom) & Top Force (FTop) and hit the calculate button. Here is how the Buoyant Force given Bottom and Top Force calculation can be explained with given input values -> 3.3 = 15.67-12.37.

What is Buoyant Force given Bottom and Top Force?
The Buoyant Force given Bottom and Top Force formula is defined as the difference between Net downward force and net upward force. It is a common experience that an object feels lighter and weighs less in a liquid than it does in air. This can be demonstrated easily by weighing a heavy object in water by a waterproof spring scale. Also, objects made of wood or other light materials float on water. These and other observations suggest that a fluid exerts an upward force on a body immersed in it. This force that tends to lift the body is called the buoyant force. The buoyant force is caused by the increase of pressure with depth in a fluid. Thus, we conclude that the buoyant force acting on the plate is equal to the weight of the liquid displaced by the plate. For a fluid with constant density, the buoyant force is independent of the distance of the body from the free surface. It is also independent of the density of the solid body and is represented as Fbuoyant = FBottom-FTop or Buoyant Force = Bottom Force-Top Force. Bottom Force is defined as the gauge pressures at the bottom surface of the plate. It acts upward on the bottom surface of the plate & Top Force is defined as the gauge pressures at the top surface of the plate. It acts downward on the top surface of the plate.
