(1) The inlet velocity Vị is known. Neglect friction losses and determine the manometer reading h in terms of Vi ( the velocity at position 1), H, L , D, d, and the densities of water and mercury. The left hand branch of the manometer is exposed to the atmosphere as is the nozzle exit (position 2). d L D Water H h PHg Mercury

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.
