It consists of a transparent header tank and 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 bell mouth entry to the flow visualization pipe. Flow through this pipe is regulated using a control valve at the discharge end. The water flow rate through the pipe can be measured using the volumetric tank (or volumetric cylinder). Velocity of the water can therefore be determined to allow the calculation of the Reynolds Number. A dye injection system is installed on top of the header tank so that flow pattern in the pipe can be visualized. Osborne Reynolds is an experiment that introduce to the student on the fluid flow through the industrial piping system in a small scale flow which include of laminar flow, transition flow and turbulent flow. The flow involves from a transparent header tank and the flow visualization pipe which is the header tank is provided with a diffuser and stilling materials at the bottom to be responsible for a constant head of water designated for discharged through a bell mouth entry of the flow visualization pipe. Flow through this  pipe is designed by using a control valve at the discharge end. The water flow rates out measured by observing the water out at the volumetric tank or also known as volumetric tank while the velocity of the water determined to obtain the Reynolds Number. The  pattern of the water flow were visualized through the dye injection system which installed on the top of the header tank. The Reynolds Number calculated follow through formula that discover from the British engineer which is:   Pipe Flow Conditions For water flowing in pipe or circular conduits, L is the diameter of the pipe. For Reynolds number less than 2100, the pipe flow known as laminar flow. For Reynolds number from 2100 to 4000 the pipe flow will be considered as the transitional flow. Turbulent occur when Reynolds number is above 4000. The viscosity of the fluid also defines the characteristic of the flow becoming laminar or turbulent. Fluid with higher viscosity is easier to reach a turbulent flow condition. The viscosity of fluid is also reliant on the temperature.    FACULTY : ENGINEERING  TECHNOLOGY EDITION: LABORATORY: BIOPRODUCT FACILITY DESIGN LAB REVISION NO: EXPERIMENT: PRE- COMMISSIONING, COMMISSIONING AND START-UP EFFECTIVE DATE: AMENDMENT DATE: Laminar Flow Laminar flow symbolized a steady flow condition where all streamlines follow parallel  paths, there being no contact (mixing) between shear planes. Under this condition the dye observed will remain as a solid, straight and easily identifiable component of flow. Transitional Flow Transitional flow is a combination of laminar and turbulent flow with turbulence in the center of the pipe, and laminar flow near the edges. Each one of these flows acts in different behaviors in terms of their frictional energy loss while flowing, and have different equations that predict their performance. Turbulent Flow Turbulent flow indicates an unsteady flow condition where streamlines act together causing the shear plane breakdown and mixing of the fluid. In this condition the dye observed will come to be disperse in the water and mix with the water. The observed dye will not be identifiable at this point.      FACULTY : ENGINEERING  TECHNOLOGY EDITION: LABORATORY: BIOPRODUCT FACILITY DESIGN LAB REVISION NO: EXPERIMENT: PRE- COMMISSIONING, COMMISSIONING AND START-UP EFFECTIVE DATE: AMENDMENT DATE: 2.0 MATERIAL AND APPARATUS Plan well and carry out the activities of pre-commissioning, commissioning and start-up for the equipment. 6 9 7 Figure 1: Unit Assembly of Osborne Reynolds Demonstration (Model: FM11)   1) Dye reservoir 6) Overflow tube, V3 2) Dye control valve, V4 7) Water inlet valve, V1 3) Dye injector 8) Bell mouth 4) Head tank 9) Water outlet valve, V2 5) Observation tube 1 2 3 4 5 8
