| Abstract: | The viscosity of gaseous R143a was measured with a Maxwell-type oscillating disk viscometer from 299 to 338 K at pressures of up to 2.69 MPa.The estimated uncertainty of the reported viscosity is ±2.0%.Correlation for the viscosity was presented,and the maximum absolute deviation and mean absolute deviation of the measured data from the equation were 0.97% and 0.20%,respectively. |
