A device used to switch electrical current at a selectable setpoint temperature.
The natural, convective movement of air or water due to differences in temperature. In solar passive design a thermosyphon collector can be constructed and attached to a house to deliver heat to the home by the continuous pattern of the convective loop (o ...
Thermosyphon systems use a separate storage tank located above the collector. Liquid warmed in the collector rises naturally above the collector, where it is kept until it is needed. The liquid can be either water or a glycol solution. If the fluid is wat ...
A layer of semiconductor material, such as copper indium diselenide or gallium arsenide, a few microns or less in thickness, used to make solar photovoltaic cells.
Metal or wooden peg inserted in gunwale of a boat for an oar to heave against when rowing without crutch or rowlock.
A phrase with a nautical derivation, meaning a man under the influence of drink or unsteadiness through drink.
Sailing with three sheet ropes running free, thus making the ship barely able to keep headway and control. Drunk.
Alternating current in which three separate pulses are present, identical in frequency and voltage, but separated 120 degrees in phase.
The lowest value of a measured quality at which a sensor responds. Compare to tracking.
Threshold stress for stress-corrosion-cracking. The critical gross section stress at the onset of stress-corrosion cracking under specified conditions.
(1) The relationship between the current density at a point on a surface and its distance from the counter electrode. The greater the ratio of the surface resistivity shown by the electrode reaction to the volume resistivity of the electrolyte, the better ...
The part of a rotating element that counteracts any inherent thrust developed by the impellers.
