Piping Flow and Immersed Body Flow
Introduction:
The friction factor (f) is used to account for the frictional losses that occur during the flow of fluids through pipes. On the other hand, the drag coefficient (CD) is used to quantify the resistance experienced by an object moving through a fluid. Let's analyze the given statements to determine their accuracy.
Analysis of Statements:
P: f accounts only for the skin friction
This statement is true. The friction factor (f) is primarily used to account for the skin friction, which is the resistance caused by the viscous shear stress between the fluid and the pipe surface.
Q: CD accounts only for the form friction
This statement is false. The drag coefficient (CD) accounts for both the skin friction and the form friction. The form friction arises due to the pressure difference between the front and rear surfaces of an object moving through a fluid.
R: CD accounts for both skin friction and form friction
This statement is true. As mentioned earlier, the drag coefficient (CD) takes into account both the skin friction and the form friction. It provides an overall measure of the resistance experienced by an object in a fluid flow.
S: Both f and CD depend on the Reynolds number
This statement is true. The friction factor (f) and the drag coefficient (CD) are both influenced by the Reynolds number. The Reynolds number is a dimensionless parameter that characterizes the flow regime. It is defined as the ratio of inertial forces to viscous forces in the fluid flow.
T: For laminar flow through a pipe, f doubles on doubling the volumetric flow rate
This statement is false. For laminar flow through a pipe, the friction factor (f) does not depend on the volumetric flow rate. It is primarily determined by the nature of the flow (laminar or turbulent) and the pipe roughness.
Conclusion:
Based on the analysis of the statements, the correct answer is option 'C': P, R, and S. The friction factor (f) accounts for skin friction, the drag coefficient (CD) accounts for both skin friction and form friction, and both f and CD depend on the Reynolds number.
