The formula to calculate the Darcy Friction Factor is:
\[ f = \frac{0.0791}{Re^{0.25}} \]
Where:
The Darcy Friction Factor, also known as the Darcy-Weisbach friction factor, is a dimensionless quantity used in fluid dynamics to represent the resistance to flow in a pipe. It is a key parameter in the Darcy-Weisbach equation, which relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow. The factor depends on the roughness of the pipe’s interior surface and the Reynolds number, a measure of the flow’s turbulence.
Let's assume the following value:
Using the formula:
\[ f = \frac{0.0791}{10000^{0.25}} = 0.00791 \]
The Darcy Friction Factor is 0.00791.
Let's assume the following value:
Using the formula:
\[ f = \frac{0.0791}{50000^{0.25}} = 0.00532 \]
The Darcy Friction Factor is 0.00532.
