PRESSURISED PIPE CALCULATOR
The darcy-weisbach equation is used to analyse pressurised pipes. For open channel flow see the Mannings calculator.
- hL = Head loss (m)
- f = Darcy friction factor
- K = Minor loss factor
- L = Pipe length (m)
- D = Hydraulic diameter (m)
- V = Average flow velocity (m/2)
- g = Acceleration due to gravity (m/s²)
