Abstract:
A method for determining optimum ambient pressure that minimizes the energy required to form a bubble of a given volume in a liquid, the method comprising the steps of:entering a first pressure and a second pressure; calculating a first boiling temperature corresponding to said first pressure; calculating a second boiling temperature corresponding to said second pressure; entering a surface tension of said bubble at said first boiling temperature and said second boiling temperature; entering a heat of vaporization (Hv) value of said liquid at said first boiling temperature and said second boiling temperature; calculating a first energy required to vaporize said liquid at said first pressure; calculating a second energy required to vaporize said liquid at said second pressure; determining whether said first energy required at said first pressure is greater than said second energy required at said second pressure; and forming said bubble at the pressure corresponding to the lower of said first energy or said second energy.
