Measurement of fluid speed based on Bernoulli's principle (a) A manometer is connected to
two that are closed together and small enough not to disturb the flow. The tube is open at
the end facing the flow. A dead spot having zero speed created there. Tube 2 has an opening
on the side, and so the fluid has speed V across the opening; thus, pressure there drops.
The difference in pressure at the manometer is 
a Prandtl tube, also known as a pitot tube.
