We were discussing theÂ difference
between Notches and Weirs,Â discharge
over a triangular notch or weir,Â expression
for discharge over a rectangular notch or weir,Â advantage
of triangular notch or weir over rectangular notch or weir, discharge
over a trapezoidal notch and also discharge overa stepped notch Â in the subject of fluid
mechanics, in our recent posts.Â

Now we will go ahead to find out the
kinetic energy correction factor and momentum correction factor, in the subject
of fluid mechanics, with the help of this post.Â

###
**Kinetic energy correction factor **

Kinetic energy correction factor is
basically defined as the ratio of kinetic energy of the flow per second based
on actual velocity across a section to the kinetic energy of the flow per
second based on average velocity across the same section.Â

Kinetic energy correction factor will be
displayed by the symbol Î± and will be written mathematically as mentioned here.Â

**Kinetic energy correction factor, Î±**=

(K.E. per second based on actual
velocity) / (K.E. per second based on average velocity)Â

###
**Momentum correction factor **

Momentum correction factor is basically
defined as the ratio of momentum of the flow per second based on actual
velocity across a section to the momentum of the flow per second based on
average velocity across the same section.Â

Momentum correction factor will be
displayed by the symbol Î² and will be written mathematically as mentioned here.Â

**Momentum correction factor, Î²**=

(Momentum per second based on actual
velocity) / (Momentum per second based on average velocity)Â

Now we will go ahead to start a new
topic in the subject of fluid mechanics i.e. Power absorbed in viscous flow.Â

Do you have any suggestions? Please
