Reference Density (expression)

Can someone tell me what is wrong with this expression for Reference Density:
Reference Density = p/(R0*T) where R0=8314.5 [m^2 s^-2 K^-1](pressue is assumed to be in kg/ms2 I guess). I got a warning telling that final unit is kg/m3K2, instead of kg/m3. Thank you, Marco |

There's nothing wrong with the expression shown above... check you didn't enter it as p/R0*T, since that could be interpreted as (p/R0)*T which would give the warning message. However, I'm not sure if you are allowed to set a variable Reference Density, I think may have to evaluate to a constant, so it can't depend on the solution variables p and T. I could be wrong here though. Mike
