Abstract

A new rotating-body viscometer for the low-pressure region was presented. A viscosity dependent offset was compensated by calibrating the viscometer. The viscosity of carbon dioxide was measured at low pressures. Measurements were carried out from T=(253.15 to 473.15)K with p ≤ 1.2MPa. The relative expanded combined uncertainty (k=2) was Ur,c(η) =(0.20 to 0.41)%.
