Buoyancy calculator helps to determine the buoyant force of a flowing liquid. Buoyant force is the gravitational body force which acts on a fluid of non-uniform density. The buoyant force on an object is equal to the weight of the fluid displaced by the object.This can be calculated using the given formula.

B = $\rho$ Vg

Where

**is the buoyant force**

*B***is the density of fluid**

*$\rho$***is the volume**

*V***is the acceleration due to gravity**

*g***Step 1:**From the question, note down the given measures

**Step 2:**Plug these values in the given equation

B = $\rho$ Vg

**Find out the required quantity**

### Solved Examples

**Question 1:**The density of a liquid is given as 900kg/m

^{3}and the volume is also given as 2m

^{3}. Calculate its buoyant force?

**Solution:**

Given that,

$\rho$ = 900kg/m

^{3}and V = 2m

^{3}and g = 9.8m/s

Buoyancy force equation is

B = $\rho$ Vg

B = 900$\times$2$\times$9.8 = 17640 N

**Question 2:**If the density and buoyant force of a liquid is 1000kg/m

^{3}and 11550 N respectively, calculate the volume of the liquid?

**Solution:**

Given that,

$\rho$ = 1000kg/m

^{3}and V = ? and g = 9.8m/s, B = 11550 N

Buoyancy force equation is

B = $\rho$ Vg

V = $\frac{B}{\rho g}$

V = $\frac{11550}{1000\times9.8}$ = 1.178 m
