dew point-bubble point calculator
TRANSCRIPT
Objectives of the ProgramThe objectives of this program are:
1. To calculate dew point – bubble point temperature and pressure as well as the component’s composition;
2. To provide a more accurate way of calculation;
3. To minimize time and effort during iterations.
