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.

The characteristics of a centrifugal pump operating at 1000 rpm is given by H=41-2000². The system characteristics may be represented by H= 24 +3200². The units for volume flow rate Q and head H are m³/s and m, respectively. When two pumps operating at 1000 rpm and connected in parallel are used, with the system characteristics remaining unchanged, the operating volume flow rate through the system is m³/s.
