Thorpe tube flowmeter. A Thorpe tube flowmeter, a type of variable-area flowmeter, or a rotameter, is an instrument used to directly measure the flow rate of a gas in medical instruments. It consists of a connection to a gas source, a needle valve opened and closed by turning an attached dial for control of flow rate, a float resting in a clear ...
Flow measurement. Flow measurement is the quantification of bulk fluid movement. Flow can be measured using devices called flowmeters in various ways. The common types of flowmeters with industrial applications are listed below: Obstruction type (differential pressure or variable area)
A mass flow meter, also known as an inertial flow meter, is a device that measures mass flow rate of a fluid traveling through a tube. The mass flow rate is the mass of the fluid traveling past a fixed point per unit time. The mass flow meter does not measure the volume per unit time (e.g. cubic meters per second) passing through the device; it ...
Magnetic flow meter. A magnetic flow meter ( mag meter, electromagnetic flow meter) is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to ...
Gas meter. A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas. Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility. Gases are more difficult to measure than liquids, because measured volumes are ...
Fanno flow is the adiabatic flow through a constant area duct where the effect of friction is considered. [ 1] Compressibility effects often come into consideration, although the Fanno flow model certainly also applies to incompressible flow. For this model, the duct area remains constant, the flow is assumed to be steady and one-dimensional ...
A court ruling could permit the construction of a new reservoir to feed the water-starved Panama Canal, but the project might take six years to build, the managers of the waterway said Monday. The ...
The P.H. Hanes Knitting Company complex was listed on the National Register of Historic Places in 2005. [3] [4] In 1965 the Hanes Corporation was formed from the consolidation of two Hanes companies: P. H. Hanes Knitting Company and Hanes Hosiery Mills Company [5] In 1979, the corporation became part of Consolidated Foods (later renamed Sara Lee).
