WebEquation (1) is only valid at laminar conditions where Reynolds Number is less than 2300. For turbulent conditions where Reynolds Number exceeds 4000 the Colebrook equation should be used to calculate the friction coefficient. In practice laminar flow is only actual for viscous fluids - like crude oil, fuel oil and other oils. WebThe default values are for air flow 20 o C, 1.2 kg/m 3 and 6 m/s - the same as in the example above. The friction coefficient can be calculated with the Colebrook equation. This calculator is generic and can be used with SI and Imperial units. Just substitute the values with the values for the actual application.
