Cheng Huiting-Hao Wenbin universal gas pipeline pressure drop equation

Thread Content

The Cheng Huiting-Hao Wenbin universal gas pipeline pressure drop equation is the only universal and rigorous theoretical equation so far. Although it has just been launched (2021, 2022), it is already: 1) Natural gas ； 2) Air ； 3) Its universality and accuracy have been verified in the calculation of pressure drop in water steam pipelines. These verifications are compared with the calculation results of the special formulas for the pressure drops of these three gas pipelines. Since there are no specific assumptions and approximations in the establishment process of the Cheng Huiting-Hao Wenbin universal gas pipeline pressure drop equation, it should be suitable for the calculation of pipeline pressure drop for more gas types. Some forward-thinking design institutes and engineering companies, especially private companies, immediately used it, thereby liberating them from the ocean of diverse, cumbersome and changeable formulas. Many universities are working to bring this equation into courseware, classrooms, and plans to include it in university textbooks. Universality is manifested in: 1. Any gas ； 2. Any pipe specification ； 3. Any pressure ； 4. Any pressure drop range. you just need to learn * With this formula, you can more accurately calculate the pressure drop of all gas pipelines. You may no longer need to study the hundreds of relatively rough empirical formulas in history. * They are.
