The Design of Reynolds Number Apparatus with Demonstration

Abstract

The Reynolds number apparatus has been designed. The idea of this device enters all the details of life, all trains, wing of aircraft and ships, and each of them has a specific characteristic. Besides, the Reynolds number apparatus is designed to study the characteristics of fluid such as the velocity of the fluid, discharge, friction factor and the roughness coefficient. (Reynolds number) device was manufactured and fully took all information and details on how to use the device through the lessons given and reliable sources. The results from the device were taken such as the time and the amount of volume in liters. Some types of flow remained in their condition and others changed from transitional flow to turbulent flow. Based on the results, the relation between Reynolds numbers and friction factor are analyzed and the correlation between the time and the discharge are calculated too to investigate the analysis through this apparatus. The results proved all three types of flow and the relationship between Reynolds and friction factor is considered to be in linear regression. The relationship between discharge and flow velocity and Reynolds number is a 'direct' relationship. The increasing in the friction factor has displayed with decreasing in the value of Re. The R2 fit the model with value near to 0.90 or less. Also, the linear model is fit the relation between discharge and time, the increasing in the flowrate showed with decreasing the time. In some cases, the nonlinear fit the model with R2 near to 70 or less.
