•    The equipment used by Reynolds consists of a tank containing water and fitted with a horizontal glass tub,  through which water can flow.

•    There is small overhead tank containing a coloured liquid having the same specific gravity as that of water.

•    The flow of water from the water tank through the glass tube can be regulated by adjusting the regulating value. By regulating the flow of water, its velocity through the glass tube is regulated.

•    As long as the velocity in the glass tube is maintained at a sufficiently low value, the colure band will remain a thin straight line flowing along the entire length of the glass tube. Such flow is laminar flow.

•    If the velocity is now gradually increased till a value reaches at which the colour band breaks and mixes with water. Such flow is turbulent flow.
