The momentum correction factor (β) for the viscous flow through a circular pipe is
Momentum correction factor is defined as the ratio of momentum of the flow per second based on actual velocity to the momentum of the flow per second based on average velocity across a section. For turbulent flow the momentum correction factor is slightly higher than one near to 1.2 and for laminar,Read more
