Inserir no projetoP2140400Sistema de treinamento em medida de viscosidade com viscosímetro de queda de esfera

Principle

Due to internal friction among their particles, liquids and gases have different viscosities. The viscosity, a function of the substance's structure and its temperature, can be experimentally determined, for example, by measuring the rate of fall of a ball in a tube filled with the liquid to be investigated.

Tasks

Measure the viscosity

  1. of methanol-water mixtures of various composition at a constant temperature,
  2. of water as a function of temperature and
  3. of methanol as a function of temperature.

From the temperature dependence of the viscosity, calculate the energy barriers for the displace ability of water and methanol.
