The County Commissioners are so excited to finally be able to share this news with everyone! Crystal Steel is a wonderful company that will create 126 new, good paying jobs in Caroline County and invest $4 million at their Federalsburg location. Thanks to our local Caroline Economic Development Corp. staff, the staff and elected officials of Federalsburg, and the team at the Maryland Department of Commerce for their help in making this happen!
Incompressible flows do not have such a variation of density. The key differentiation between compressible and incompressible is the velocity of the flow. A fluid such as air that is moving slower than Mach 0.3 is considered incompressible, even though it is a gas. A gas that is run through a compressor is not truly considered compressible (in the thermodynamic sense) unless its velocity exceeds Mach 0.3.
First, just as the water starts to get hot, a lot of bubbles will form down the walls of your water container. These bubbles are AIR. Normally water has a lot of air dissolved on it. This is what allows breathing to fishes and other aquatic beings. The solubility of gases decreases when the temperature is raised, and that why the dissolved air bubbles out from the water. Then, as the boiling point of water is reached (100 degrees Celsius or 212 degrees Fahrenheit), water vapor starts to form inside the liquid in the form of bubbles.
