<p>PROBLEM TO BE SOLVED: To provide a method for exactly deciding the pressure optimum for working of a device which generates air bubbles within a vessel. SOLUTION: The method or deciding the optimum atmosphere pressure for minimizing the energy required for forming the air bubbles of the prescribed volume in liquid includes a step for inputting the first pressure and the second pressure, a step for calculating a first boiling temperature, a step for calculating a second boiling temperature, a step for inputting the surface tension of the air bubbles, a step for inputting the vaporization heat value (HV) at the boiling temperature of the liquid, a step for calculating the first energy in order to vaporize the liquid, a step for calculating the second energy in order to vaporize the liquid, a step for deciding whether the first energy is greater than the second energy regarded to be necessary under the second pressure or not and a step for forming the air bubbles under the pressure corresponding to the lower of either the first energy or the second energy.</p> |
