Pressure Loss from Fittings - Expansion and Reduction in Pipe Size
Pressure Loss from Fittings - Expansion and Reduction in Pipe Size

This article provides methods to calculate the K-value (Resistance Coefficient) for determining the pressure loss cause by changes in the area of a fluid flow path. These types of pressure drops are highly dependent on the geometry and are not usually covered in simple pressure loss estimation schemes (such as a single k-value, equivalent length etc.)
