Flow Channel Apparatus
Product Code : EL-EFFCA-11076
Quick answer: The flow channel apparatus makes streamlines visible as water flows steadily around drag bodies of different shapes. Students see where the lines crowd together and the flow speeds up, and where they spread and the flow slows, around each body. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How it is used in teaching
A streamline is a line that is tangent to the velocity everywhere along it. In steady flow the pattern does not change with time, so each streamline is also the path a fluid particle follows. Because no flow crosses a streamline, the flow between two neighbouring lines is constant; where they squeeze together the velocity must rise, and where they spread it falls.
Placing bodies of different shape in the channel shows these ideas directly. Flow divides at a stagnation point on the front of each body and speeds up around its sides; behind a bluff shape it leaves a wake, while a streamlined shape lets the lines close up smoothly. This links the picture to drag, to Bernoulli's equation and to the design of piers, vanes and aerofoils.

Frequently asked questions
What does the flow channel apparatus demonstrate?
It demonstrates streamlines as the flow passes around drag bodies of different shapes, showing how the velocity changes around each one.
Why does closer streamline spacing mean faster flow?
The same flow passes between two neighbouring streamlines, so where they come closer the water must move faster to get through.
