In Fluid mechanics or in general, water implies liquid water and it is modelled as incompressible fluid. In thermodynamics, compressed liquid represents the phase of the liquid. Any liquid that is not about to vaporize is called as \"Compressed liquid\". Even after heat addition, water remains in liquid phase till the temperature reaches boiling point of water at that pressure. As the liquid reaches boiling point (saturation temperature), liquid starts to vaporize i.e., a phase change process from liquid to vapor is about to take place. A liquid that is about to vaporize is called as \"Saturated Liquid\". Hence, when the temperature is below the saturation temperature at the given pressure, the properties of water are obtained by compressed liquid tables. Note: Please do not get confused with compressed liquid tables to compressible tables. It is actually \"compressed liquid\" table representing the phase of the liquid.
