Question 1:

The momentum correction factor (β) is used to account for:

Options:

Change in direction of flow

Change in total energy

Non-uniform distribution of velocities at inlet and outlet sections

Change in mass rate of flow

Correct Answer: Option 3 (Solution Below)

Solution:

Explanation:

Momentum correction factor, β: it 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.

Where, A = area of cross-section, dA = small cross section of area, v = average velocity, u = actual velocity

It is considered to take into the effect of the non-uniform distribution of velocities or flow at inlet and outlet section through pipes.
