The image above represents the fluid velocity. To calculate fluid velocity, five essential parameters are needed, and these parameters are Porosity (e), Pressure (-ΔP), Distance of Bed (d), Viscosity (μ), and Length of Bed (l).
The formula for calculating fluid velocity:
uc = 0.0055(e³/(1 – e)²)(-ΔPd²/μl)
Where:
uc = Fluid Velocity
e = Porosity
-ΔP = Pressure
d = Distance of Bed
μ = Viscosity
l = Length of Bed
Let’s solve an example;
Find the fluid velocity when the porosity is 20, the pressure is 10, the distance of bed is 12, the viscosity is 14 and the length of bed is 11.
This implies that;
e = Porosity = 20
-ΔP = Pressure = 10
d = Distance of Bed = 12
μ = Viscosity = 14
l = Length of Bed = 11
uc = 0.0055(e³/(1 – e)²)(-ΔPd²/μl)
That is, uc = 0.0055(20³/(1 – 20)²)(10(12)²/(14)(11))
uc = 0.0055(8000/(-19)²)(10(144)/154)
uc = 0.0055(8000/361)(1440/154)
So, uc = 0.0055(22.16)(9.35)
uc = 1.139
Therefore, the fluid velocity is 1.139 m/s.
