Question

Relation between gravitational force, buoyant force and drag force on a particle in liquid

Answer 1

Answer:

Buoyant force and drag force on a particle in liquid relation between gravitational force ...

Answer 2

Answer:

In Newtonian gravity, the attractive force between two point-like masses  M  and  m  is given by

F=GMm/r2

The buoyant force on an object equals the weight of the fluid it displaces. In equation form, Archimedes’ principle is

FB=wfl,

 

where  FB  is the buoyant force and  wfl  is the weight of the fluid displaced by the object.

Drag Force Equation  

F = 0.5 C ρ A V2

Notation

Our calculation allows you to use a variety of units with all of the conversions completed internally. The units below are consistent units for the drag force equation.

A = Reference area as (see figures below), m2.

C = Drag coefficient (see figures below), unitless.

F = Drag force, N.

V = Velocity, m/s.

ρ = Density of fluid (liquid or gas), kg/m
