Definitions, online calculator and figures and tables with water properties like density, specific weight and thermal expansion coefficient of liquid water at temperatures ranging 0 to 360°C (32 to 680°F).
Example - water is a liquid where the volumetric expansion coefficient changes a lot with temperature. Water has its highest density and smallest volume at 4 o C (39.2 o F) . The volumetric coefficient for water is negative below 4 o C and indicates that the a volume decreases when temperature moves from 0 o C ( 32 o F ) to 4 o C .
25 sie 2014 · The volumetric expansion of a liquid is given by the following equation. ΔV =V0βΔT Δ V = V 0 β Δ T. where β β is the coefficient of thermal expansion and ΔT Δ T is the change in temperature. Here's a link to a nice table containing coefficients of expansion for water, both pure and salinated.
Thermal expansion in hot water systems: This article defines thermal expansion in water equipment in response to temperature, and explains the concomitant increase in system pressure. We show how to calculate hot water pressure increase in water heaters and boilers as a function of the increase in water temperature.
In general, liquids expand on heating, except cold water; below 4 °C it contracts, leading to a negative thermal expansion coefficient. At higher temperatures it shows more typical behavior, with a positive thermal expansion coefficient.
25 wrz 2023 · The thermal expansion of water can be calculated using the formula: ΔV = V₀ * β * ΔT Where: ΔV = Change in volume V₀ = Initial volume β = Coefficient of thermal expansion of water ΔT = Change in temperature
