Measuring point for compressor acceptance test. Temperature at
the compressor inlet flange.
T3
Measuring point for compressor acceptance test. Temperature
before an orifice or nozzle, downstream of compressor discharge.
Temperature
Is the property of a substance that gauges the potential or
driving force for the flow of heat.
Temperature absolute
The temperature of a body referred to the absolute zero, at
which point the volume of an ideal gas theoretically becomes zero.
(Fahrenheit scale is minus 459.67°F / Celsius scale is minus
273.15°C).
Temperature
discharge
Is the temperature existing at the discharge port of the
compressor.
Temperature inlet
Is the temperature at the inlet flange of the compressor.
Temperature intake
The toal temperature at the intake flange of the compressor.
Temperature rise
ratio
Is the ratio of the computed isentropic temperature rise to
the measured total temperature rise during compression.
Temperature static
The actual temperature of a moving gas stream. It is the
temperature indicated by a thermometer moving in the stream with
the same velocity as the stream.
Temperature total
The temperature which would be measured at the stagnation
point if a gas stream were stopped, with adiabatic compression
from the flow condition to the stagnation pressure.
Theoretical power
The power required to compress a gas isothermally through a
specified range of pressures.
Thermal compressor
is an ejector used to compress waste or exhaust steam or any
other gas through a moderate range of compression above
atmospheric pressure.
Thermal mass
Material that stores energy, although mass will also retain
coolness. The thermal storage capacity of a material is a measure
of the material's ability to absorb and store heat.
Thermodynamics
first law of
The amount of work done on or by a system is equal to the
amount of energy transferred to or from the
system.
Thermodynamics
second law of
Heat cannot, of itself, pass from a colder to a hotter
body.
Thrust balancing
device
The part of a rotating element that counteracts any inherent
thrust developed by the impellers.
Tilting pad
A type of journal bearing in centrifugal air compressors.
Torr
A unit of pressure used with vacuum pumps, equal to 1mm of
mercury and 133.32 Pascal's.
Total package input
power
The total electrical power input to a compressor, including
drive motor, cooling fan, motors, controls, etc.
Torque
Torsional moment or couple. It usually refers to the driving
couple of a machine or motor.
Trunk compressor
A compressor belonging to the group of displacement
reciprocating compressors.
Trunnion
A device for mounting cylinders.
Tugger
An air operated device for hoisting or pulling. Similar to a
slusher or winch
Tundish
A receptacle, open to atmosphere, that is used to used to
collect condensate. For example, two or three drain pipes from
various filters may be discharging into a funnel. In this case the
funnel is a tundish.
Two stage compressor
Machines in which air or gas is compressed from initial
pressure to an intermediate pressure in one or more cylinders or
casings.
Two step control
Load/unload control system that tries to maximizes compressor
efficiency by matching air delivery and air demand. Compressor is
operated at full load or idle
