摘要：
The pipe flow equations for diameter and discharge are given separately for laminar and turbulent flows; and no equation is available for transition between these flows. As the diameter or discharge is unknown, it is not possible to find the flow regime. Thus, the appropriate equation can not be applied. Presented herein are full range equations for diameter and discharge. These equations are valid in laminar as well as turbulent flows and the transition in between.
