摘要: The design and operation of a new vibrating-wire viscometer for the measurement viscosity liquids at pressures up to 100 MPa are described. instrument is based on complete theory so that it possible make absolute measurements with an associated error only few parts in one thousand. Absolute n-hexane reported 298.15 K 80 MPa. overall uncertainty data estimated be ±0.5%, estimate confirmed by comparison values slightly inferior accuracy.
