Superficial Gas Velocity Formula
The following formula is used to calculate a Superficial Gas Velocity.
Us = Q / A
- Where Us is the Superficial Gas Velocity (m/s)
- Q is the volumetric flow rate of the phase (m^3/s)
- A is the cross-sectional area of the medium (m^2)
To calculate a Superficial Gas Velocity, divide the flow rate of the phase by the cross-sectional area of the medium.
What is Superficial Gas Velocity?
Definition:
A superficial gas velocity is an estimation of the speed at which fluid or gas moves through an object.
How to calculate Superficial Gas Velocity?
Example Problem:
The following example problem outlines how to calculate Superficial Gas Velocity.
First, determine the volumetric flow of the gas in the phase. For this example, the flow rate is 50m^3/s.
Next, determine the cross-sectional area of the medium. The cross-sectional area in this example is 25 m^2.
Finally, calculate the Superficial Gas Velocity using the formula above:
Us = Q / A
Us = 50 / 25
Us = 2 m/s
