How to Calculate and Solve for Galileo’s Number | Fluidization
Last Updated on July 24, 2021
The image above represents galileo’s number.
To compute for galileo’s number, two essential parameters are needed and these parameters are 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 the galileo’s number when the porosity at minimum fluidization is 12 and the reynold’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
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
Ga = -5.729 + 0.0364
Ga = -5.692
Therefore, Galileo’s number, Ga is -5.69.
