WebMahendra Verma. An ActiveX component, MoodyChart is written in Visual Basic 6.0 to calculate frictional factor for fluid flow in a pipeline using one of the three implicit and four explicit forms ... WebFlow in Pipes Running Full. The Colebrook White equation calculates the velocity ( v) of flow through a circular pipe running full using the below equation; This is the acceleration due to gravity, typically taken as 9.81m/s 2 at sea level. This is the internal diameter of the pipe being considered. This is effectively the slope of pipe in m/m.
