Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

A Pitot-static probe was used to measure the velocity distribution in a water tunnel. The two pressure lines from the probe were connected to a U-tube manometer which uses a liquid of specific gravity 1.7. The maximum velocity expected in the water tunnel was 2.3 m/s. Your job was to select an appropriate U-tube from a manufacturer which supplies manometers of different heights. The cost increases significantly with manometer height. Which of these should you purchase?
