The Effects Of Temperature And Pressure Variation On The Process Of Cooking Foods, Benjamin M. Aldrich

Electronic Theses and Dissertations

It is generally known that water has a definite boiling temperature for each pressure to which its surface is subjected and that wet steam generated in a closed vessel maintains a definite temperature-pressure relation. Under each condition of temperature and pressure the steam contains a fixed amount of available energy stored as heat and called, "Heat Content" the value of which is usually based upon an arbitrary zero fixed a 32 degrees F., the freezing temperature of water under one atmosphere of pressure.
