coefficient of heat conduction
21Multi-layer insulation — Closeup of Multi layer insulation from a satellite. The metal coated plastic layers and the scrim separator are visible. Multi layer insulation, or MLI, is thermal insulation composed of multiple layers of thin sheets often used on spacecraft. It …
22Measuring instrument — Captain Nemo and Professor Aronnax contemplating measuring instruments in Twenty Thousand Leagues Under the Sea …
23Biot number — The Biot number (Bi) is a dimensionless number used in unsteady state (or transient) heat transfer calculations. It is named after the French physicist Jean Baptiste Biot (1774 1862), and relates the heat transfer resistance inside and at the… …
24Dynamic 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… …
25Thermal conductivity — In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It appears primarily in Fourier s Law for heat conduction.First, we define heat conduction by the formula::: H=frac{Delta Q}{Delta t}=k …
26Vacuum tube — This article is about the electronic device. For experiments in an evacuated pipe, see free fall. For the transport system, see pneumatic tube. Modern vacuum tubes, mostly miniature style In electronics, a vacuum tube, electron tube (in North… …
27Pressurized water reactor — (PWRs) (also VVER if of Russian design) are generation II nuclear power reactors that use ordinary water under high pressure (superheated water) as coolant and neutron moderator. The primary coolant loop is kept under high pressure to prevent the …
28Cooling load temperature difference calculation method — Contents 1 CLTD/CLF/SCL Cooling Load Calculation Method 2 History 3 Application 4 Explanation of Variables …
29Thermal contact conductance — In physics, thermal contact conductance is the study of heat conduction between solid bodies in thermal contact. The thermal contact conductance coefficient, hc, is a property indicating the thermal conductivity, or ability to conduct heat,… …
30Glass-ceramic — materials share many properties with both glass and more traditional crystalline ceramics. It is formed as a glass, and then made to crystallize partly by heat treatment. Unlike sintered ceramics, glass ceramics have no pores between crystals.… …
