With the volume of fluid temperature changes and changes in general, temperature increases, the volume expansion. Fluid to the thermal expansion of this attribute to that.

Thermal expansion is a time when the fluid temperature changes the relative size of its rate of change to symbols Said,that is

120

in the formula V DDFluid original size due to temperature changes and expansion of the volume;

TDDFluid temperature value.

Table 1-3 gives the coefficient of thermal expansion of water.
