Water expands about four percent when heated from room temperature to its boiling point. And finally, our friends over at engineerintoolbox.com remind us that calculating the cubic thermal or volumetric expansion of water (and some osther substances) is a bit tricky because the actual coefficient of expansion of water varies as the water temperature changes. In this chart, the left side or vertical axis is water density, measured in kilograms / cubic meter or kg/m3 , and the horizontal axis is water temperature measured in oC. 1 What is the expansion rate of water to steam? Thermal Properties of Radon Radon - Melting Point and Boiling Point Melting point of Radon is -71C. Net expansion volume of water when heated can be expressed as, Vnet = (v1 / v0 ) - 1 (1), Vnet = expansion volume of water (ft3, m3), V0 = specific volume of water at initial (cold) temperature (ft3/lb, m3/kg), V1 = specific volume of water at operating (hot) temperature (ft3/lb, m3/kg). Generally, the expansion of water into steam depends greatly on temperature and atmospheric pressure. But two different events affect the pressure and density of water in the tank: So you can see that there are two forces, both temperature and pressure, at work at once. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. This means that under ideal conditions, 1 part of liquid water expands to 1700 times the volume as steam when boiled. If the water system is closed (say by a check valve or a blockage) the result is an increase in water system pressure as well. The result can be a dripping temperature/pressure relief valve that can in turn become clogged, rendering the water heating system unsafe, damaging the water heater tank, or even leading to an explosion. Obviously, at the same pressure, the higher the temperature the lower the density of water vapor. In that article you'll find our excerpt from a water heater manufacturer (Bradford White) that notes thatA 40 gallon water heater with 80 PSI line pressure will build to a pressure of 145 PSI with a temperature increase of 16F.
