Friction factor vs reynolds number

WebDec 22, 2024 · For example, if you want to compare a small-scale model (e.g., a model of an airplane) with a real situation, you should keep the Reynolds number the same. The Reynolds number is the ratio of … The Haaland equation was proposed in 1983 by Professor S.E. Haaland of the Norwegian Institute of Technology. It is used to solve directly for the Darcy–Weisbach friction factor f for a full-flowing circular pipe. It is an approximation of the implicit Colebrook–White equation, but the discrepancy from experimental data is well within the accuracy of the data. The Haaland equation is expressed:
