Explanation:
Reynolds Number is a dimensionless number used to predict flow patterns in different fluid flow situations. It is calculated as the ratio of inertial forces to viscous forces within a fluid. The Reynolds Number can provide information about the type of flow, whether it is laminar or turbulent.
The friction factor is a measure of the resistance to flow in a fluid system. It is used in calculating the pressure drop across a pipe or duct, which is important in determining the energy efficiency of a system. The friction factor depends on the Reynolds Number and the relative roughness of the pipe.
Relative roughness is the ratio of the height of the irregularities on the surface of the pipe to the diameter of the pipe. It is a measure of the roughness of the pipe's interior surface. The value of relative roughness is important in determining the friction factor.
In this question, the Reynolds Number is given as 1500, and two pipes with different values of relative roughness are considered. The question asks which pipe will have a higher friction factor. The correct answer is option 'C', which states that the friction factor will be the same in both pipes.
The reason for this is that the Reynolds Number is the same in both pipes, and the friction factor depends only on the Reynolds Number and the relative roughness, not on the individual values of Reynolds Number or relative roughness. Therefore, the friction factor will be the same in both pipes.
Conclusion:
In summary, the friction factor will be the same in two different pipes with Reynolds Number of 1500 and relative roughness of 0.001 and 0.002, respectively. This is because the friction factor depends on the Reynolds Number and the relative roughness, and not on the individual values of Reynolds Number or relative roughness.
