Thermodynamic properties of compressed liquids

TL;DR Summary

required properties for compressed liquids

Hi All,
I have review my thermodynamic notes (~35 year ago..), and I could not able to restore how to get thermodynamic properties (u,h,s,v ..) for compressed liquids. I have found properties tables for compressed liquids ( for water..) but unfortunately the data starts at 5MPa. What if I look for properties of compressed liquids (let say water) at pressures smaller than 5MPa? let say 0.5MPa?

Here's a table that starts at 2.5 MPa. http://lngacademy.weebly.com/uploads/2/0/8/5/20853058/steam_tables.pdf

Those values do not change much from the values of saturation.

Thank you,
It was helpfull

Equations that might be helpful to you are
$$\left(\frac{\partial u}{\partial P}\right)_T=(P\beta-T\alpha)v$$
$$\left(\frac{\partial h}{\partial P}\right)_T=(1-T\alpha)v$$
$$\left(\frac{\partial s}{\partial P}\right)_T=-\alpha v$$where v is the specific volume, $\alpha$ is the volumetric coefficient of thermal expansion, and $\beta$ is the bulk compliance:$$\alpha=\left(\frac{\partial \ln{v}}{\partial T}\right)_P$$and $$\beta=-\left(\frac{\partial \ln{v}}{\partial P}\right)_T$$In these equations, away from the critical point, you can treat the specific volume as constant, and values of the coefficient of thermal expansion and bulk compliance (or its reciprocal, the bulk modulus) are in tables.

Sorry,
I'm not femiliar with latest formulas you noted above..
Thanks any way
