The pressure drop in circular pipes is calculated using Darcy-Weisbach equation: The flow is considered laminar when Re<2300. In a laminar flow the friction factor f is calculated by f=64/Re. For Re>2300 the flow is considered turbulent and the friction factor is calculated using the Colebrook interpolation function:
