The image above represents Galileo’s number. Two essential parameters are needed to calculate Galileo’s number: Porosity at Minimum Fluidization (emf) and Reynold’s Number at Minimum Fluidization (Re’mf).
The formula for calculating Galileo’s number:
Ga = 150(1 – emf/emf³)Re’mf + (1.75/emf³)Re’mf²
Where:
Ga = Galileo’s Number
emf = Porosity at Minimum Fluidization
Re’mf = Reynold’s Number at Minimum Fluidization
Let’s solve an example;
Find Galileo’s number when the porosity at minimum fluidization is 12 and the Reynolds’s number at minimum fluidization is 6.
This implies that;
emf = Porosity at Minimum Fluidization = 12
Re’mf = Reynold’s Number at Minimum Fluidization = 6
Ga = 150(1 – emf/emf³)Re’mf + (1.75/emf³)Re’mf²
That is, Ga = 150(1 – 12/12³)6 + (1.75/12³)6²
Ga = 150(-11/1728)6 + (1.75/1728)36
Ga = 150(-0.0063)6 + (0.00101)36
So, Ga = -5.729 + 0.0364
Ga = -5.692
Therefore, Galileo’s number, Ga is -5.69.
