摘要: The viscosity of seven gases (Ar, CH4, C3H8, N2, SF6, CF4, C2F6) was determined by interpreting frequency-response data from a Greenspan acoustic viscometer with detailed model developed Gillis, Mehl, and Moldover. contains parameter ∈ r that characterizes the viscous dissipation at ends viscometer's duct. It difficult to determine accurately dimensional measurements; therefore, adjusted fit helium on 298 K isotherm (0.6 MPa
