Study Notes
Turbine Installation and Condenser
- Air is removed from the condenser in a turbine installation using a vacuum pump.
Vena Contracta Location
- The vena contracta is located at the point where the fluid jet issuing through a hole in a plate has the minimum cross-sectional area.
Turbine in a Fluid Loop
- The primary purpose of a turbine in a fluid loop is to transfer energy from the fluid to the turbine.
Indirect (Secondary) Miscellaneous Methods to Measure Flow
- Examples of indirect (secondary) miscellaneous methods to measure flow include: ultrasonic flowmeters, Coriolis flowmeters, and vortex flowmeters.
- Not an example of indirect (secondary) miscellaneous methods to measure flow is: Venturi meter.
Reynolds Number Similarity
- Reynolds number similarity is not expected in cases where there are significant differences in geometric scale, flow regimes, or fluid properties.
