The image above represents average velocity. To calculate average velocity, five essential parameters are needed, and these parameters are Constant of Proportionality (k1), Change in Pressure (ΔP), Hydraulic Radius (Rh), Length of Pipe (L), and Viscosity (η).
The formula for calculating average velocity:
v = k1ΔPRh² / Lη
Where:
v = Average Velocity | Tube-Bundle Theory
k1 = Constant of Proportionality
ΔP = Change in Pressure
Rh = Hydraulic Radius
L = Length of Pipe
η = Viscosity
Let’s solve an example;
Find the average velocity when the constant of proportionality is 10, the change in pressure is 5, the hydraulic radius is 2, the length of pipe is 4 and the viscosity is 8.
This implies that;
k1 = Constant of Proportionality = 10
ΔP = Change in Pressure = 5
Rh = Hydraulic Radius = 2
L = Length of Pipe = 4
η = Viscosity = 8
v = k1ΔPRh² / Lη
v = (10)(5)(2)² / (4)(8)
So, v = (10)(5)(4) / 32
v = 200 / 32
v = 6.25
Therefore, the average velocity is 6.25 m/s.
