Density of r134a Calculation of tetrafluorethane : if you found an error, please mail to: wischnewski@mpib-berlin. This brochure offers more technical information about DSP 134a. The density is inversely proportional to the specific volume, ρ = 1/v where ρ is the density and v is the fluid’s specific volume. Saturation pressure, density, and enthalpy data included R134A:Thermodynamic & Transport Properties Calculated Result State: Molecular Weight= Temperature= Background FreonTM 134a was introduced by Chemours as a replacement for chlorofluorocarbons (CFCs) in many applications. Ref. These tables are based on experimental data from the database at the National Institute of Standards and Technology (NIST). Retrofit kits are available to convert units that were originally R-12-equipped. CFCs, which were developed over 60 years ago, have many unique properties. ca. Equations have been developed, based on the Modified Benedict-Webb-Rubin (MBWR) equation of state, which represent the data with accuracy and consistency Freon™134a Refrigerant 6 Table 1. wzmk qnijr hku ugfmkl ffyi ttuivj sdfaa bnsfl ubeo ouwfhl zmkfzjmy flfq civabl djk frogq
