China Wholesale Liquid Surface Tension Factory – LMEC-12 Measuring Liquid Viscosity – Capillary Method – Labor
China Wholesale Liquid Surface Tension Factory – LMEC-12 Measuring Liquid Viscosity – Capillary Method – Labor Detail:
Liquid viscosity is not only widely used in engineering and production technology, but also plays an important role in biology and medicine. For example, measuring the size of blood viscosity is one of the important signs of human blood health. Compared with the falling ball method, this experiment uses the flow law of viscous fluid in the vertical capillary tube. It has the advantages of less sample quantity, different temperature points and high measurement accuracy. It is especially suitable for liquids with small viscosity coefficient, such as water, alcohol, water and so on The application of this instrument not only expands students’ knowledge, but also cultivates their experimental operation ability.
Experiments
1. Understand the Poiseuille law
2. Learn how to measure viscous and surface tension coefficients of liquid using Ostwald viscometer
