Fluid Mechanics Laboratory 2 Report Robby Joseph 14103508 1.0 Introduction This experiment was undertaken for the study of flow in pipes and the factors that affect it in both laminar and turbulent regimes. The transitional regime between laminar and turbulent flow will also be studied. The experiment was done using a pipe with a known diameter‚ and water was pumped in from a tank. Throughout the process‚ measurements of the quantity of water and time were taken as well as the hydraulic gradient

Pipe Friction Summary The purpose of this lab is to find the friction factor and Reynolds number for laminar and turbulent flow and also for values in the critical zone. Results were taken recorded and used to calculate the friction factor and Reynolds number. They were then compared with the Moody diagram. Aim This lab could be used in industry when dealing with a pipe line containing any type of liquid to calculate the Reynolds number and friction factor. It would also help in pipe

dye injector utilized to generate the required flow. A dye injection system is installed on top of the header tank so that the pattern of the flow can be visualized. The characteristic of the flow is observed‚ there are laminar‚ transition and turbulent flow. The volume of water is fixed for certain values and the times are recorded. Based on the results‚ the ranges are calculated for laminar and turbulence flow. It was proved that the Reynolds number is dimensionless by using the units only

It consists of a transparent header tank and a flow visualization pipe. The header tank is provided with a diffuser and stilling materials at the bottom to provide a constant head of water to be discharged through a bellmouth entry to the flow

upon the surface of the pipe‚ this is called Friction Loss. This type of lost depends on the shear stress due to the walls of the pipe and the fluid. It also depends in weather the fluid is laminar or turbulent. A major difference between these two flows is that due to a viscous layer created in turbulent flow the roughness of the pipe can be taken in account while in laminar flow‚ it can be neglected because that layer is not created. Many factors are taken in account when we want to measure the energy
