| Feb 3 at 3:00 | comment | added | J.O. | Guys, guys, all I want to know is what happens to pressure when a fluid goes supercritical. The rest of this is irrelevant and over my head. Does pressure go through the roof when the fluid in a closed, filled vessel goes supercritical, or does double the temperature produce double the pressure regardless of crossing the supercritical point? Does the pressure inside a nuclear power plant double if the temperature (in Kelvins) doubles, of what? | |
| Feb 3 at 2:50 | comment | added | J.O. | continued: --d C, so they never get too close to 374 C. I know that zirconium combines with the oxygen in steam and supercritical water, releasing hydrogen; don't care; I need to know what happens to the pressure if that plant overheats and its coolant goes supercritical. Again, if your plant is running at 325 C, and it overheats to 650 C, does the pressure double, or what? | |
| Feb 3 at 2:32 | comment | added | J.O. | Over my head, guys. I can't copy and paste the chart on page 2, here www-pub.iaea.org/MTCD/publications/PDF/P1500_CD_Web/htm/pdf/… | |
| Feb 2 at 14:44 | comment | added | Mithoron | At such high pressures supercrit. fluids are liquid-like and there is no phase transition at crossing crit. temp. The pressure would increase in fashion that is neither linear nor exponential, or any simple function afaict. | |
| Feb 2 at 14:36 | comment | added | Mithoron | Huh, one would need a line of constant density drawn on P-V phase diagram to tell, but I don't think you'd notice anything at this temp. Why not? Because there would be no vapor phase and pressure would get over crit. value long before crit. temp. | |
| Feb 2 at 7:21 | comment | added | Poutnik | The vessel would crack due liquid water thermal dilation long before reaching the critical T. | |
