See the below image for the Weight liquid temperature conversion diagram. v = specific volume (m 3 /kg) Volume and change in Temperature. When temperature increases – most liquids expands: dV = V 1 – V 0 = V 0 β dt = V 0 β (t 1 – t 0) (3) where . dV = V 1 – V 0 = change in volume – difference between final and initial volume (m 3) β = volumetric temperature expansion coefficient (m 3 /m 3 o C)
Weight of liquid calculator uses Weight of liquid = Specific weight of liquid*Discharge to calculate the Weight of liquid, The Weight of liquid formula is defined as the product of specific weight of liquid and discharge (volume of the liquid). Weight of liquid is denoted by W symbol.
The density of a liquid will change with temperature and pressure. The density of water versus temperature and pressure is indicated below: See also Water – Density, Specific Weight and Thermal Expantion Coefficient, for online calculator, figures and tables showing changes with temperature.
