Abstract
The shear viscosity coefficients of saturated and compressed liquid 1, 1,1,2-tetrafluoroethane (R134a), 2,2-dichloro-1,1,1-trifluoroethane (R 123) and 1,1-dichloro-1-fluoroethane (R141b) have been measured with a torsional crystal viscometer at temperatures between 170 and 320 K an d at pressures up to 30 MPa. The fluidities (reciprocal viscosity) inc rease linearly with molar volume at fixed temperature and increase wea kly with temperature at fixed volume. We have correlated our data usin g empirical fluidity-volume-temperature equations and have compared th e data of others with the equations.
