Josef "Joschi" Pöhs (14 March 1912 – 30 December 1943) was a Luftwaffe ace and recipient of the Knight's Cross of the Iron Cross during World War II.The Knight's Cross of the Iron Cross was awarded to recognise extreme battlefield bravery or successful military leadership.
The Knight's Cross of the Iron Cross and its higher grades were based on four separate enactments.The first enactment, Reichsgesetzblatt I S. 1573 of 1 September 1939 instituted the Iron Cross (Eisernes Kreuz), the Knight's Cross of the Iron Cross and the Grand Cross of the Iron Cross (Großkreuz des Eisernen Kreuzes).
The solubility of gas obeys Henry's law, that is, the amount of a dissolved gas in a liquid is proportional to its partial pressure. Therefore, placing a solution under reduced pressure makes the dissolved gas less soluble. Sonication and stirring under reduced pressure can usually enhance the efficiency.
For a small amount of entrained gas in a drilling fluid, the degasser can play a major role of removing small bubbles that a liquid film has enveloped and entrapped. [1] In order for it to be released and break out the air and gas such as methane, H 2 S and CO 2 from the mud to the surface, the drilling fluid must pass through a degassing technique, and it can be accomplished by the equipment ...
Sparging introduces a gas that has little or no partial pressure of the gas(es) to be removed, and increases the area of the gas-liquid interface, which encourages some of the dissolved gas(es) to diffuse into the sparging gas before the sparging gas escapes from the liquid. Many sparging processes, such as solvent removal, use air as the ...
Inert gas continues to be taken up until the gas dissolved in the diver is in a state of equilibrium with the breathing gas in the diver's lungs, (see: "Saturation diving"), or the diver moves up in the water column and reduces the ambient pressure of the breathing gas until the inert gases dissolved in the tissues are at a higher concentration ...
Once dissolved, distribution of the dissolved gas is by perfusion, where the solvent (blood) is circulated around the diver's body, and by diffusion, where dissolved gas can spread to local regions of lower concentration when there is no bulk flow of the solvent. Given sufficient time at a specific partial pressure in the breathing gas, the ...
Before opening, the gas above the drink in its container is almost pure carbon dioxide, at a pressure higher than atmospheric pressure. After the bottle is opened, this gas escapes, moving the partial pressure of carbon dioxide above the liquid to be much lower, resulting in degassing as the dissolved carbon dioxide comes out of the solution.
