Parameters
|
|
|
output
|
-
|
symbol or string for the desired output quantity
|
|
fluid
|
-
|
symbol or string representing the medium
|
|
opts

(optional) equation of the form useunits = true or useunits = false

Description
|
|
|
•
|
The Props1SI function interrogates the CoolProp library for thermophysical data.
|
|
•
|
The output parameter can be any of the numerical thermophysical properties in the Quantities and Maple-specific aliases columns of the following table, whenever that property makes sense for the given fluid. In almost all circumstances, you can use either one of the names used by the CoolProp library, or an alias defined by the Maple package.
|
|
•
|
If you supply the useunits = true option (which can be shortened to just useunits), then the result will always have the appropriate unit. If you supply useunits = false (the default), the result will never have a unit.
