Darcy-Weisbach Equation

The Darcy-Weisbach equation calculates the pressure loss or energy loss as fluid flows through a pipe due to friction. It relates the pressure drop to the flow velocity, pipe length, diameter, fluid properties, and a friction factor that accounts for roughness and flow type. Essentially, it helps engineers determine how much energy is required to move fluid through a pipe, considering how pipe surface roughness and flow conditions affect resistance. This understanding is crucial for designing efficient piping systems in water supply, oil, and gas industries.
