Reynolds's Number is a dimension less number used by engineers to determine type of Fluid Flow and testing on scale down models of airplanes, ships etc.
Apparatus consists of a constant head tank and a small tank. The constant head tank has a horizontal/vertical transparent tube with a and a flow control valve at the discharge side. The velocity of water is varied by the flow control valve. When the dye is introduced then laminar or turbulent nature of the flow can be visualized.Specifications:
