Developing A Systematic Direct Method of Discharge and Diameter Calculations Required to Solve Simple Piping Systems Problems

摘要

Solving simple piping system problems to reach a concluded behavior analysis of an existing piping system; or to reach solutions of system designing problems is essential in lots of agricultural engineering applications; as well as it is for hydraulic, petroleum, or civil engineering applications. This study was conducted to find a new non computational method, as the computational solutions for these problems are not always available; beside that they are built up depending on experimentally derivedcorrelation equations like Haaland equation, Barr equation, Swamee equations and consequently; depending on the iterative method or even trial and error method using Moody curves.This new non computational method is easier, faster, and relatively more accurate as it reduces the human error might occur due to the repetitive use of Moody curves with each trial till problem is solved. A linear relation was found between Reynolds number and the friction factor f in there logarithmic form, this relation helped in reaching the desired intercept point on Moody curves using one assumption to solve Category II problems, and two assumptions to solve Category III problems. Then; a mathematical relation was used to reach the required discharge Q or diameter & in a systematic direct way with no need for more assumptions.
