72industrial glass — Introduction solid material that is normally lustrous and transparent in appearance and that shows great durability under exposure to the natural elements. These three properties lustre, transparency, and durability make glass a favoured… …
73Air handler — An air handling unit; air flow is from the right to left in this case. Some AHU components shown are: 1 Supply duct 2 Fan compartment 3 Vibration isolator ( flex joint ) 4 Heating and/or cooling coil 5 Filter compartment 6 Mixed (recirculated +… …
74Superconducting Radio Frequency — (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra low electrical loss of the superconductor yields RF resonators with extremely high quality factors, or Q . For example, it… …
75Water heating — is a thermodynamic process using an energy source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking, cleaning, bathing, and space heating. In industry, both hot water and water heated to steam have… …
76heating — I Process of raising the temperature of an enclosed space. Heat can be delivered by convection, radiation, and thermal conduction. With the exception of the ancient Romans, who developed a form of central heating, most cultures relied on direct… …
77Natural convection — Bénard cells. Natural convection is a mechanism, or type of heat transport, in which the fluid motion is not generated by any external source (like a pump, fan, suction device, etc.) but only by density differences in the fluid occurring due to… …
78thermodynamics — thermodynamicist, n. /therr moh duy nam iks/, n. (used with a sing. v.) the science concerned with the relations between heat and mechanical energy or work, and the conversion of one into the other: modern thermodynamics deals with the properties …
79Nuclear meltdown — Three of the reactors at Fukushima I overheated, causing core meltdowns. This was compounded by hydrogen gas explosions and the venting of contaminated steam which released large amounts of radioactive material into the air.[1] …
