The limiting oxygen concentration (LOC), [1] also known as the minimum oxygen concentration (MOC), [2] is defined as the limiting concentration of oxygen below which combustion is not possible, independent of the concentration of fuel. It is expressed in units of volume percent of oxygen. The LOC varies with pressure and temperature.
The brand was so well known in the refrigeration field in the early-to-mid-1900s, that many Americans called any refrigerator a Frigidaire regardless of brand. [6] In France, Canada, and some other French-speaking countries or areas, the word Frigidaire is often in use as a synonym today, and in transcribed form in Serbo-Croatian also ...
Compressed air dryers are special types of filter systems that are specifically designed to remove the water that is inherent in compressed air. The compression of air raises its temperature and concentrates atmospheric contaminants, primarily water vapor, as resulting in air with elevated temperature and 100% relative humidity.
The IPC is the most widely used plumbing code in the United States and is also used as the basis for the plumbing code of several other countries [citation needed].Wide adoptions are important as they help reduce manufacturer and end-user costs by allowing the use of materials across a wide user base, thus allowing economies of scale in the production of materials used in construction.

With the publication of the 2003 Edition of the Uniform Plumbing Code, another significant milestone was reached. For the first time in the history of the United States, a plumbing code was developed through a true ...
An 80 US gal (300 L; 67 imp gal) electric storage tank water heater was able to have a minimum energy factor of 86% under the pre-2015 standard, while under the 2015 standard, the minimum energy factor for an 80-gallon electric storage tank water heater is now 197%, which is only possible with heat pump technology. This rating measures ...
Tanks can be used to hold materials as diverse as milk, water, waste, petroleum, chemicals, and other hazardous materials, all while meeting industry standards and regulations. [1] Storage tanks are available in many shapes: vertical and horizontal cylindrical; open top and closed top; flat bottom, cone bottom, slope bottom and dish bottom.
Most commonly used for non-potable water on farms however can be an outer duct for roadside utilities. Worksafe encourages the use of a 5mm wide or larger colored stripe to indicate the content of the black duct using one of the color codes above. A plain black microduct or 2-pair telephone cable is often used by Chorus for premises drop cables.
