Kinetic Energy Correction and Momentum Correction Factors

Q. Laminar flow occurs between extensive stationary plates. The kinetic energy correction factor is nearly

1. 1.0
2. 1.5
3. 2.0
4. 2.3

Q. Given that, as flow takes place between two parallel static plates, the velocity midway between the plates is 2 m/s, the Reynolds number is 1200 and the distance between the plates is 10 cm, which of the following statements are true?

1. The velocity of the boundary is 1 m/s.

$2.{\text{The rate of flow is 0.1 m}}^3\text{/s/metre width.}$

3. The flow is turbulent.

4. The energy correction factor is 2.0.

Select the correct answer using the codes given below:

1. 2 and 3
2. 2 and 4
3. 1 and 3
4. 1, 2, 3 and 4

Q. Consider the following velocity profiles in pipline:




Among these profiles, the momentum correction factor would be

1. Least in 4
2. Highest in 1
3. More in 3 than that for 2
4. The same in 1, 2, 3 and 4
