Coefficient of volumetric expansion

WebThermal expansion is the increase, or decrease, of the size (length, area, or volume) of a body due to a change in temperature. Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids. Linear thermal expansion is.

WebThe linear thermal expansion coefficient is defined as: where L is a particular length measurement and dL/dT is the rate of change of that linear dimension per unit change in temperature. The volumetric thermal expansion coefficient is the most basic thermal expansion coefficient, and the most relevant for fluids. When calculating thermal expansion it is necessary to consider whether the body is free to expand or is constrained. If the body is free to expand, the expansion or strain resulting from an increase in temperature can be simply calculated by using the applicable coefficient of thermal expansion. If the body is constrained so that it cannot expand, then internal stress will be … ウルフ 伸ばしかけ https://boldinsulation.com
