4 lis 2012 · Critical Pressure: The pressure required to liquify a substance vapor at its critical temperature. Critical point: The end point of the pressure-temperature curve that designates conditions under which a liquid and its vapor can coexist. At higher temperatures, the gas cannot be liquefied by pressure alone.

4 lis 2012 · Thermodynamic properties of water: Boiling temperature (at 101.325 kPa): 99.974 °C = 211.953 °F. Bulk modulus elasticity : 2.15 x 10 9 Pa or N/m 2. Critical temperature : 373.946 °C = 705.103 °F.
4 lis 2012 · Online calculator, figures and tables with water saturation (vapor) pressure at temperatures ranging 0 to 370 °C (32 to 700°F) - in Imperial and SI Units.
The critical point of water occurs at 647.096 K (373.946 °C; 705.103 °F) and 22.064 megapascals (3,200.1 psi; 217.75 atm; 220.64 bar). [ 3 ] In the vicinity of the critical point, the physical properties of the liquid and the vapor change dramatically, with both phases becoming even more similar.
1 ATM (atmospheric pressure) = 14.7 psi at sea level if we double the pressure (Boyles Law), the psi in the tank we are using as an example would increase to about 29.4 psi. 20 gallons of air = 2.67 cubic feet at 1 ATM. The D'Arcy-Weisbach equation for pressure and head loss is discussed at AIR DUCT THEORY: The D'Arcy-Weisbach formula, and
1st Part: Water Saturation Pressure For Fahrenheit (°F) – Calculator, Example, Chart. Using this 1st calculator, you insert temperature in °F, and get the vapor pressure of water in terms of kPa, PSI, mmHg, Bar, atm, torr. We look at the 68°F example specifically.
