Get pressure on predetermined T and specific V using ThermodynamicData?

Hello!

My problem is that I would like to draw a steam T-s diagram in Wolfram cloud.
When I use “ThermodynamicData”, I only can get the specificVolume on predetermined pressure and temperature, but my specific volume is fix → 0.699 m^3/kg.
So I would like to make something that gives me enthropy values on a Temperature range 402 Kelvin to 473 Kelvin.

Thanks for help!

It looks like Mathematica (I’m using 14.0) accepts “Density”.

ThermodynamicData["Water", "Entropy", {"Temperature" -> 
   Quantity[450, "Kelvin"], "Density" -> Quantity[1.431, "kg/m^3" ]}]

With answer

 Quantity[7223., ("Joules")/("Kelvins" "Kilograms")]

Will that work for your need? If not, I’d like to understand why.
