Veracity and Satisfiability Condition of State Equation of Bubble Liquid

Calculations have been performed to confirm the suitability of the equation of state of a gas-liquid mixture proposed in this article. The dependence of the dimensionless radius of the air bubble, of the pressure in the bubble, of gas temperature on the dimensionless time and analogical dependence for the case when the pressure went down abruptly at room temperature in the water depicted. Calculations have shown that the obtained equations of state are in good agreement with the results known in the literature.

Keywords:
