Friction factor for fully developed turbulent flow through a rough circular pipe
Friction factor for fully developed turbulent flow through a rough circular pipe depends on two main factors:
Reynolds number
- Reynolds number plays a significant role in determining the friction factor for turbulent flow. It is a dimensionless quantity that characterizes the flow regime in a pipe.
- The friction factor increases with an increase in Reynolds number, indicating higher flow resistance in turbulent flow.
Relative roughness
- Relative roughness is another crucial factor that influences the friction factor for turbulent flow.
- It is defined as the ratio of the height of the pipe wall roughness to the diameter of the pipe.
- Higher relative roughness leads to increased friction factor, as the roughness of the pipe wall disrupts the flow and causes more resistance.
Therefore, the friction factor for fully developed turbulent flow through a rough circular pipe depends on both the Reynolds number and relative roughness. These parameters interact to determine the overall flow characteristics and resistance in the pipe. It is essential to consider both factors when analyzing turbulent flow in pipes to accurately predict pressure drops and flow rates.
