Study Notes
Fluid Flow
- To move a liquid from point A to point B, the energy at point A must be higher than at point B.
- The flow through a line can be increased by increasing the pressure at point A or decreasing the pressure at point B.
- The difference in pressure between two points at the same elevation caused by the flow of fluid in a system is called pressure drop or delta P.
- The delta P for the first pipe is 3 psig.
- The delta P for the second pipe is 4 psig.
- When delta P increases, the rate of flow increases. When delta P decreases, the rate of flow decreases.
- True. The rate of flow must have the element of volume and a unit of time. Mass flow measurements are more accurate than volume flow measurements because they are not affected by changes in density or temperature.
- Velocity is faster upstream of an orifice plate.
- Venturi tubes, pitot tubes, and flow nozzles all use pressure differential to determine flow rate.
- The French mathematician, mechanical engineer, and scientist responsible for the mass flow meter in use today is Gaspard Gustave de Coriolis.
