He used linseed oil as the thermometric fluid. [6] 1701 — Ole Christensen Rømer made one of the first practical thermometers. As a temperature indicator it used red wine. (Rømer scale), The temperature scale used for his thermometer had 0 representing the temperature of a salt and ice mixture (at about 259 s).
The Boyce MotoMeter was a simple and innovative device. For the first time, drivers had information about the engine temperature while operating the car. Sometimes, however, it failed to warn drivers about engine overheating in time to prevent damage. Motometers were at first aftermarket devices. Later, vehicle builders (not only car ...
Such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer. Another type of thermometer that is not really used much in practice, but is important from a theoretical standpoint, is the gas thermometer. Other important devices for measuring temperature include:
July 2019: IBM buys Red Hat for $34 billion in one of the largest software acquisitions in history. Leading up to the sale, Red Hat employs 13,360 people worldwide and reports yearly revenue of $3 ...
A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury ...
Motor oil is used for the lubrication, cooling, and cleaning of internal combustion engines. Motor oil may be composed of only a lubricant base stock in the case of mostly obsolete non-detergent oil, or a lubricant base stock plus additives to improve the oil's detergency, extreme pressure performance, and ability to inhibit corrosion of engine ...
Motor oil, a common lubricant.. A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move.
Red Hat Czech s.r.o. is a research and development arm of Red Hat, based in Brno, Czech Republic. [97] The subsidiary was formed in 2006 and has 1,180 employees (2019). [98] Red Hat chose to enter the Czech Republic in 2006 over other locations due to the country's embrace of open-source. [99]
