    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.
