The default value for each of these new parameters is 0.0. A value of zero effectively disables the
pressure and temperature pipe volume compensation routine. When entering a value for the thermal
expansion coefficient and modulus of elasticity, keep in mind that the numeric entry already includes an
exponent multiplier. For the Thermal Expansion Coefficient the multiplier is 10
-6
and for the Modulus of
Elasticity the multiplier is 10
6
.
Typical values for each parameter are shown below:
