fluid temperature
61Heat deflection temperature — The heat deflection temperature or heat distortion temperature (HDT, HDTUL, or DTUL) is the temperature at which a polymer or plastic sample deforms under a specified load. This property of a given plastic material is applied in many aspects of… …
62Ultra-high-temperature processing — or (less often) ultra heat treatment (both abbreviated UHT) is the partial sterilization of food by heating it for a short time, around 1 2 seconds, at a temperature exceeding 135°C (275°F), which is the temperature required to kill spores in… …
63Reduced temperature — In thermodynamics, the reduced temperature of a fluid is its actual temperature, divided by its critical temperature:T r = {T over T c}where the actual temperature and critical temperature are expressed in absolute temperature scales (either… …
64transition temperature — The temperature at which there is a transition in the organization of, for example, the phospholipids of a membrane where the transition temperature marks the shift from fluid to more crystalline. Usually determined by using an Arrhenius plot of… …
65Quantum fluid — A quantum fluid can refer to a cluster of valence electrons moving together after they undergo fermionic condensation. Under extremely high pressures and low temperatures electrons may condense into a quantum fluid. In such a state, electrical… …
66Second-order fluid — A second order fluid is an extension of the model of a first order fluid.It can be written as :mu {operatorname{eff(dot gamma, T) = exp left( A 0 + A 1 ln(dot gamma) + A 2 T + A 3 (ln(dot gamma))^2 + A 4 T ln(dot gamma) + A 5 T^2 ight) where dot… …
67critical temperature — /ˌkrɪtɪkəl ˈtɛmprətʃə/ (say .kritikuhl tempruhchuh) noun 1. Physics (of a gas) the temperature above which a gas cannot be liquefied by an increase of pressure alone. 2. Metallurgy a. the highest temperature at which it is possible to separate… …
68critical temperature — noun 1. a. : the temperature of a substance in its critical state : the highest temperature at which it is possible to separate substances into two fluid phases (vapor and liquid) b. : the transition temperature of a solid from one allotropic… …
69ambient temperature — The surrounding air temperature. The temperature of fluid (usually air) which surrounds object on all sides …
70Supercritical fluid chromatography — is a form of normal phase chromatography that is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules. It can also be used for the separation of chiral compounds. Principles are similar to those… …
