The image above represents the ratio of the linear velocity of the gas. To calculate the ratio of linear velocity of gas, three essential parameters are needed and these parameters are Porosity (e), Bubble Velocity (ub) and Sedimentation Velocity (uc).
The formula for calculating ratio of linear velocity of gas:
α = e(ub/uc)
Where:
α = Ratio of Linear Velocity of Gas
e = Porosity
ub = Bubble Velocity
uc = Sedimentation Velocity
Let’s solve an example;
Find the ratio of linear velocity of gas when the porosity is 8, the bubble velocity is 10 and the sedimentation velocity is 14.
This implies that;
e = Porosity = 8
ub = Bubble Velocity = 10
uc = Sedimentation Velocity = 14
α = e(ub/uc)
So, α = 8(10/14)
α = 8(0.714)
α = 5.71
Therefore, the ratio of linear velocity of gas is 5.71.
Calculating the Porosity when the Ratio of Linear Velocity of Gas, the Bubble Velocity and the Sedimentation Velocity are Given
e = α x uc / ub
Where:
e = Porosity
α = Ratio of Linear Velocity of Gas
ub = Bubble Velocity
uc = Sedimentation Velocity
Let’s solve an example;
Find the porosity when the ratio of linear velocity of gas is 30, the bubble velocity is 5 and the sedimentation velocity is 3.
This implies that;

α = Ratio of Linear Velocity of Gas = 30
ub = Bubble Velocity = 5
uc = Sedimentation Velocity = 3
e = α x uc / ub
That is, e = 30 x 3 / 5
e = 90 / 5
e = 18
Therefore, the porosity is 18.

Calculating the Bubble Velocity when the Ratio of Linear Velocity of Gas, the Porosity and the Sedimentation Velocity is Given
ub = α x uc / e
Where:
ub = Bubble Velocity
α = Ratio of Linear Velocity of Gas
e = Porosity
uc = Sedimentation Velocity
Let’s solve an example;
Find the bubble velocity when the ratio of linear velocity of gas is 20, the porosity is 2 and the sedimentation velocity is 4.
This implies that;
α = Ratio of Linear Velocity of Gas = 20
e = Porosity = 2
uc = Sedimentation Velocity = 4
That is, ub = α x uc / e
ub = 20 x 4 / 2
So, ub = 80 / 2
ub = 40
Therefore, the bubble velocity is 40.

Calculating the Sedimentation Velocity when the Ratio of Linear Velocity of Gas, the Porosity and the Bubble Velocity are Given
uc = ub x e / α
Where:
uc = Sedimentation Velocity
α = Ratio of Linear Velocity of Gas
e = Porosity
ub = Bubble Velocity
Let’s solve an example;
Find the sedimentation velocity when the ratio of linear velocity of gas is 10, the porosity is 9 and the bubble velocity is 6.
This implies that;
α = Ratio of Linear Velocity of Gas = 10
e = Porosity = 9
ub = Bubble Velocity = 6
uc = ub x e / α
That is, uc = 6 x 9 / 10
uc = 54 / 10
uc = 5.4
Therefore, the sedimentation velocity is 5.4.
