How do we calculate?
The economic diameter range is found with the Bresse formula D = K × √Q (K = 0.9-1.2). Starting from this range, the first standard size with a velocity not exceeding 1.5 m/s for pumped lines and 2.5 m/s for gravity lines is selected. The loss is calculated with Darcy-Weisbach (roughness 0.1 mm).
