For laminar flow, the value of kinetic energy correction factor is:
- 1
- 1.33
- 2
- 2.7
Answer: Option C. 2
For laminar flow, the value of kinetic energy correction factor is 2.
Solution
Kinetic energy correction factor: The proportion of kinetic energy based on actual velocity to kinetic energy based on average velocity is called kinetic energy correction factor.
α=1/A∫(u/v)3dA
Where, A = area, v = average velocity, u = local velocity at distance r.
For laminar flow in circular pipes, the value of kinetic energy correction factor is, α =2
