Abstract

FIELD: measurement technology. SUBSTANCE: process refers to technology of measurement of viscosity factor of fluid while conducting laboratory work in physics at higher educational institutions of various types. In compliance with known process of determination of viscosity of fluids by value of turning angle of viscosimetric body coupled to cylinders of different lengths is set in rotational motion by electric motor. Permanent coaxial magnets are attached to ends of viscosimetric body and magnetically controlled sealed contacts are placed in opposition to them. One of contacts is electrically connected to starting circuit and other one placed into stopping circuit of electric stopwatch Viscosity factor is calculated by formula, where N is modulus of twisting of viscosimetric body; c is constant of device; t1 tis value of time lagging of viscosimetric body with cylinder having length l; tis same but with cylinder having length l. EFFECT: high operational efficiency of process. 2 dwg, 1 tbl

Изобретение относится к области техники измерения коэффициента вязкости жидкостей и может быть использовано для проведения лабораторных работ в курсе физики учебных заведений различных типов. Сущность предлагаемого способа заключается в том, что в известном способе определения вязкости жидкостей по величине угла поворота вискозиметрического тела, связанного с цилиндрами различных длин, приводимых во вращательное движение электродвигателем, к концам вискозиметрического тела прикрепляют постоянные соосные магниты, а напротив них размещают магнитоуправляемые герметичные контакты, один из которых электрически подключен в цепь запуска, а второй - в цепь останова электросекундомера, при этом коэффициент вязкости вычесляют по формуле:
Figure 00000001

где N - модуль кручения вискозиметрического тела, С - постоянная прибора, t1 - величина времени запаздывания вискозиметрического тела с цилиндром длиной l1, t2 - то же самое с цилиндром длиной l2. 2 ил.The invention relates to the field of measuring the viscosity coefficient of liquids and can be used for laboratory work in the course of physics of educational institutions of various types. The essence of the proposed method lies in the fact that in the known method for determining the viscosity of liquids by the angle of rotation of a viscometric body associated with cylinders of various lengths driven by rotational motion by an electric motor, permanent coaxial magnets are attached to the ends of the viscometric body, and magnetically controlled tight contacts are placed opposite them, one of which is electrically connected to the start circuit, and the second to the stop circuit of the electric stopwatch, while the viscosity coefficient is calculated by the formula:
Figure 00000001

where N is the torsion module of the viscometric body, C is the instrument constant, t 1 is the delay time of the viscometric body with a cylinder of length l 1 , t 2 is the same with a cylinder of length l 2 . 2 ill.
