Capillary viscometer parts and functions
Webviscometer, instrument for measuring the viscosity (resistance to internal flow) of a fluid. In one version, the time taken for a given volume of fluid to flow through an opening is recorded. In the capillary tube viscometer, … WebThe model acoustic response function reduces to the Lorentzian form in the limit Q >> 1; however, the more general function is necessary to exploit the high precision of the Greenspan viscometer over the entire range of experimental conditions. Some important aspects of the model are discussed in Section 3.
