The image above represents bubble velocity. To calculate bubble velocity, two essential parameters are needed and these parameters are Velocity of Fluidizing in Air (vB) and Acceleration due to Gravity (g).
The formula for calculating bubble velocity:
ub = 0.792vB1/6g1/2
Where:
ub = Bubble Velocity
vBÂ = Velocity of Fluidizing in Air
g = Acceleration due to Gravity
Let’s solve an example;
Find the bubble velocity when the velocity of fluidizing in air is 21 and the acceleration due to gravity is 10.
This implies that;
vB = Velocity of Fluidizing in Air = 21
g = Acceleration due to Gravity = 10
ub = 0.792vB1/6g1/2
Then, ub = 0.792(21)1/6(10)1/2
ub = 0.792(1.66)(3.16)
ub = 4.160
Therefore, the bubble velocity is 4.160 m/s.
