Abstract:

This article describes the basic principles of added weight load type high pressure capillary tube pressure viscosity meters. It gives the pressure viscosity relationships for No. 10 machine oil, No. 25 transformer oil, No. 20 machine oil, and No. 20 turbine oil at different temperatures. The highest measured pressure was 0.1 GPs. The measurement temperatures were 13 deg. C, 40 deg. C, and 100 deg. C. The results of the measurement clearly show that the pressure viscosity coefficients a for these 4 types of mineral oil are lessened as they follow along with raises in temperature.
