Enter a value for all fields

The **Reduced Specific Volume** calculator computes the reduced volume(v_{r}), which is the ratio of the specific volume of a substance to the value of the specific volume at the critical point.

**INSTRUCTIONS:** Choose the preferred units and enter the following parameters.

**V**- the actual measured volume**T**- the critical temperature point for the substance_{cr}**p**- the critical pressure for the substance_{c}

**Reduced Specific Volume(v _{r}):** The volume (

The reduced properties of a fluid are a set of state variables normalized by the fluid's state properties at the fluid's critical point.^{1}

The reduced specific volume is the ratio of the specific volume of a substance to the value of the specific volume at the critical point.
