Interference of the footings. The Interference of the footings is a phenomenon that is observed when two footings are closely spaced. The buildings when are to be constructed nearby to each other, the architectural requirements or the less availability of space for the construction forces the engineers to place the foundation footings close to each other, and when foundations are placed close ...
An isobar (from Ancient Greek βάρος (baros) 'weight') is a line of equal or constant pressure on a graph, plot, or map; an isopleth or contour line of pressure. More accurately, isobars are lines drawn on a map joining places of equal average atmospheric pressure reduced to sea level for a specified period of time.
Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes. Maps using isotherms show temperature gradients, [2] which can help locate weather fronts. Isotach maps, analyzing lines of equal wind speed, [3] on a constant pressure surface of 300 or 250 hPa show where the jet stream is located.
A large number of Indian Standard (IS) codes are available that are meant for virtually every aspect of civil engineering one can think of. During one's professional life one normally uses only a handful of them depending on the nature of work they are involved in. Civil engineers engaged in construction activities of large projects usually have to refer to a good number of IS codes as such ...
Isobar may refer to: Isobar (meteorology), a line connecting points of equal atmospheric pressure reduced to sea level on the maps. Isobaric process, a process taking place at constant pressure; Isobar (nuclide), one of multiple nuclides with the same mass but with different numbers of protons (or, equivalently, different numbers of neutrons).
This makes isobars on a weather map meaningful and useful tools. [21] Altimeter setting is a term and quantity used in aviation. The regional or local air pressure at mean sea level is called the altimeter setting, and the pressure which will calibrate the altimeter to show the height above ground at a given QNH airfield. [22]
Contour line (line of constant elevation or depth, sometimes used to describe other lines of constant value) A line of constant value on a map or chart. Examples include isobar (equal barometric pressure), isotherm (equal temperature), and isohyet (equal precipitation). Isoline, an opera by André Messager
An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [ 1 ] In meteorology , wind speed , or wind flow speed , is a fundamental atmospheric quantity caused by air moving from high to low pressure , usually due to changes ...
