For laminar flow in a circular conduits, the energy correction factor ...
Kinetic energy correction factor(α):
- It is defined as the ratio of kinetic energy/second based on actual velocity to the kinetic energy/second based on average velocity.
- where A = area, V= average velocity, u= local velocity at distance r.
- In circular pipe laminar flow α = 2

For laminar flow in a circular conduits, the energy correction factor ...
Is given by the Darcy-Weisbach equation:
f = (64/Re)
Where:
- f is the energy correction factor
- Re is the Reynolds number, which is a dimensionless quantity that represents the ratio of inertial forces to viscous forces in the flow.
In laminar flow, the Reynolds number is typically less than 2,000, indicating that viscous forces dominate over inertial forces. Therefore, the energy correction factor for laminar flow in circular conduits is typically small, approaching zero.
