51Bernoulli's principle — This article is about Bernoulli s principle and Bernoulli s equation in fluid dynamics. For Bernoulli s Theorem (probability), see Law of large numbers. For an unrelated topic in ordinary differential equations, see Bernoulli differential… …
52Deadweight tester — A dead weight tester apparatus uses known traceable weights to apply pressure to a fluid for checking the accuracy of readings from a pressure gauge. A dead weight tester (DWT) is a calibration standard method that uses a piston cylinder on which …
53Potential density — The potential density of a fluid parcel at pressure P is the density that the parcel would acquire if adiabatically brought to a reference pressure P {0}, often 1 bar (100 kPa). Whereas density changes with changing pressure, potential density of …
54Altimeter — An altimeter is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth underwater. Aircraft Instrumentation… …
55List of Grounded for Life episodes — This is a list of episodes of the sitcom Grounded for Life. Contents 1 Series overview 2 Season 1: 2001 3 Season 2: 2001 2002 4 Season 3: 2002 2003 …
56Sound level meter — Type 1 Sound Level Meter (Shown: Svantek 979) Sound level meters measure sound pressure level and are commonly used in noise pollution studies for the quantification of almost any noise, but especially for industrial, environmental and aircraft… …
57Calibrated airspeed — (CAS) is the speed shown by a conventional airspeed indicator after correction for instrument error and position error. Most EFIS diplays also show CAS. At high speeds and altitudes, calibrated airspeed is further corrected for compressibility… …
58Dynamic insulation — is a form of insulation where cool outside air flowing through the thermal insulation in the envelope of a building will pick up heat from the insulation fibres. Buildings can be designed to exploit this to reduce the transmission heat loss (U… …
59Atmosphere (unit) — The Standard atmosphere is an international reference pressure defined as 101,325 Pa and formerly used as unit of pressure (symbol: atm).British Standard BS 350:2004 Conversion Factors for Units ] For practical purposes it has been replaced by… …
60Equivalent potential temperature — Equivalent potential temperature, commonly referred to as Theta e left( heta e ight), is a quantity related to the stability of a column of air in the atmosphere. heta e is the temperature a parcel of air would reach if all the water vapor in the …
