The most economical velocity in piping has shifted downward over the last 40 years
Alejandro Anaya Durand, Maria Jose de Villafranca Casas, Adriana Shunashi García Cornejo, Daniela Jara Carranza, Francisco Javier Pachec
Pipe sizing calculations include certain values that are time dependent, such as costs. While some costs rise, others decrease over time. It is the designers task to ensure that the total cost is minimized. For fluid flow calculations,heuristic criteria are often used, which is the main reason why these values must be updated from time to time. In this article, recommended velocities are updated for several materials of construction, and other velocities for new materials are calculated, using the Generaux Equation [1],...
