文摘This paper describes the principle of measuring the pressure-viscosity relation in mineral oil by the capillary method, and the ftrst experimental equipment for measuring the pressure-viscosity relation in our country—type NY-1 capillary pressuer-viscosity equipment, which is designed by the authors. The experimental investigation into four kinds of mineral oil is completed on the equipment. The range of pressure is 0 to 0.1 GPa. The experimental results show that the pressure-viscosity relations in the four kinds of mineral oil agree with the Barus equation.
