Nist Refprop: 9

The precision of REFPROP 9 makes it indispensable across several high-stakes engineering sectors: IJoT Author Guidelines - DergiPark

(REference Fluid PROPerties) is a standard reference database developed to provide the most accurate thermophysical properties for industrially important fluids and their mixtures. It is widely used in refrigeration, aerospace, and natural gas industries to optimize equipment and chemical processes. National Institute of Standards and Technology (.gov) Core Capabilities and Scope REFPROP 9.0 and its sub-version 9.1 cover over 120 pure fluids and more than 200 predefined mixtures National Institute of Standards and Technology (.gov) Fluid Types: nist refprop 9
