Abstract
The invention relates to a new method, belonging to the physical measuring field. Innovative point of the method is that a measured liquid with temperature gradient is used to realize the measurement for liquid viscous coefficient under various temperatures by measuring dropping acceleration of a ball. The method is different from the method that speed is used to deduce viscous coefficient when acceleration of small ball is zero in conventional ball dropping method. It adopts the method that by measuring on-time acceleration of small ball under different temperature point directly viscous coefficient can be deduced.
Description
The present invention is a new method in physical measurement field.The coefficient of viscosity is the important physical amount of an expression fluid properties, and the sticking phenomenon of fluid is also referred to as interior friction phenomenon.Generally speaking, the coefficient of viscosity is subjected to the influence that humidity changes.The measuring method of the coefficient of viscosity mainly contains: capillary tube technique, falling ball method, rotary process and earial drainage method.The present invention proposes the measuring method of a falling sphere measurement liquid different humidity coefficient of viscosity.The innovative point of this method is to realize measurement to the coefficient of viscosity under each state of temperature with a fluid to be measured that has a moist gradient by the method for measuring a bead whereabouts acceleration.The speed that this method is different from traditional falling ball method when measuring the bead acceleration and being zero derives the coefficient of viscosity but the coefficient of viscosity is derived in the instant acceleration of directly measuring the different temperature points bead.Structure is seen figure, and concrete device is described as follows:
1. 5. falling sphere of container
2. 6. measuring speed device of scale
3. measure 7. refrigerating plant of temperature sensor
4. 8. computing machine of well heater
