EXPERIMENTAL RESEARCH AND UNIVERSAL HYDRAULIC CALCULATION OF PIPE FLOW

摘要

It is stressed that the Colebrook's transition zone formula can be used in whole turbulent flow. Based on the popularity of computer and the adapted Colebrook's formula, in the paper a new equation for pipe-friction head loss is put forward in pipeline. With the innovation, hydraulic calculations of pipe flow would be more accurate and ideal, while the argument of how to district the turbulent and the trouble of separately calculating friction of different district may be canceled. Frictional resistance losses of 90 gasoline and 0 diesel in pipe are experimented. And errors between approximate formula and Colebrook formula are analyzed.
