REYNOULDS APPARATUS
To demonstrate the principal of laminar and turbulent flow and determination of reynoulds number for various flow rates. A water supply tank to which a glass tube is connected and enters at the center of glass tube cross section. For laminar flow condition, stick is clearly viable but in turbulent flow, the die line diffuse, controlled by valves and gives clear visualization.

VERIFICATION OF BERNOULLIES THEOREM APPARATUS
To calculate the energy & head of water at different saction, A unit consists of a transparent flow channel through which water is made to flow. The velocity of water changes as cross sectional area of channel changes. Changes of head are measured with manometric tubes connected at various tapping to the channel.
