FLUIDTYPE$

FLUIDTYPE$ returns a string that indicates the type of the fluid provided as the single argument for this function.   FLUIDTYPE$ will return one of the following strings, depending on the fluid.

'Ideal'    

'Real'    

'Brine'

'Psychrometric'

'Incompressible'

'Mixture'

Incompressible fluid refers to a substance in the Solid-Liquid Properties library. Solution refers to amixture of a solute in water that requires a concentration as one of the properties.  Psychrometric is returned for fluid AirH2O.

Note:

1. The result of the function must be assigned to a string variable, which is identified by the $ character at the end of its name.

2. The 'Brine' fluid type refers to any solution and not just a solution of a salt in water.

Example: 

$Load NASA

T1$=FluidType$(PG)

T2$=FluidType$(NH3H2O)  {provides liquid and vapor properties for ammonia-water mixtures}

T3$=FluidType$(NH3W)      {provides liquid solution properties for ammonia-water mixtures}

T4$=FluidType$(Glycerin)

T5$=FluidType$(NH3)

{Solution:

T1$='Brine'

T2$='Mixture'

T3$='Brine'

T4$='Incompressible'

T5$='Ideal'

}
