Re: High pressure Calculation. « Reply #5 on: May 30, 2017, 10:08 ». 1: I don't think so. The calculation should not be sensitive to that parameter. 2: If you set the Force convergence criterion to something very high, e.g. 1000 eV/Ang, you should get a GeometryOptimization where only the stress is really relaxed.

You'd calculate your pulse pressure using the following steps: Add the two pulse pressures together. 42 + 38 = 80. Divide the total from step 1 by the number of times you took the measurement, in this case, twice. 80 / 2 = 40. The number you got in step 2 is average pulse pressure is 40.

High barometric pressure is a pressure exceeding 1013.25 hPa, 14.7 psi, or 29.9 mmHg. This value corresponds approximately to the mean sea-level atmospheric pressure on Earth. Note that "high barometric pressure" is a relative term. At high altitudes, where the pressure can be much lower, the aforementioned pressure values …

Standard atmospheric volume of air compressed in a 1.76 cubic feet K-type cylinder at 2200 psig (2214.7 psia) can be calculated. Va = (2214.7 psia) (1.76 cu ft) / (14.7 psia) = 265 (cu ft) In other words - if air in a 1.76 cubic feet container is compressed to 2200 psig - the same air at atmospheric pressure will occupy 265 cubic feet.

This means that 14.7 psi (theoretical atmospheric pressure) will support a column of water 34 feet high. If a tube is placed in a body of water at sea level, water will rise in the tube to the same height as the water outside the tube. The atmospheric pressure will push down equally on the water surface inside and outside the tube.
