Easily calculate head loss in pipes due to fluid friction using the industry-standard Darcy-Weisbach equation. Our online Head Loss Calculator helps engineers, plumbers, and students quickly determine pressure drop for various fluid flow scenarios, ensuring efficient and reliable pipe system design and analysis. Understand major losses in industrial, plumbing, and HVAC applications.
Formula:
The calculator employs the widely accepted Darcy-Weisbach equation to determine major head loss due to friction:
hf = f × (L/D) × (V2 / 2g)
- hf: Head loss due to friction (in meters or feet)
- f: Darcy friction factor (dimensionless)
- L: Length of the pipe (in meters or feet)
- D: Hydraulic diameter of the pipe (in meters or feet)
- V: Average velocity of the fluid flow (in m/s or ft/s)
- g: Acceleration due to gravity (9.81 m/s² or 32.2 ft/s²)
