Millitorrs are generally called "microns". It is assumed among refrigeration engineers that during vacuumation processes the oils in systems worked upon, themselves, do not boil - no matter how high vacuum would be achieved. I am in doubt.
Is it feasable to achieve elavation of water to, let's say, 10 m height due to the capillary action effect ? Or the capillary diameter for that to achieve should be less than the water molecules themselves ?
You are correct. It is always assumed so as you say, but in reality the "loss in copper" current starts immediately the emf is applied.
What is form of the current on oscilloscope ? (I have never had an access to one) A slope of the resistive current, then the sine of the magnetizing current...
Roughly speaking, a generator's rotor pole passing the stator pole will indeed cause no current in a (load) coil so far the poles have not passed over their midpoint ? No matter how slow moves the rotor ?
AC, as is known, "lags" voltage in a coil and we are familiar with the drawings of the two sine waves with the 90 degree angular "shift" between them. For 50 Hz the shift translates into 5 µs "lagging" but, for instance, for 0.05 Hz AC it would indeed be 5 s ?
What I mean : frequency does not...
It seems the gas density is related to the gas residue in the vacuum % found from a Vacuum Conversion Table.
PS. Preconcern was vacuumation of systems and knowledge of how much actually there is left in a system - especially water - at different vacuum degrees.
Water may turn to ice and stay in the container - but we can add heat and not let the water to turn to ice. What else may prevent different particles be removed proportionally - both to each other and to the pressure decreasing ?
A citation: "Boyle's Law:
Doubling the pressure on a gas halves its volume, as long as the temperature of the gas and the amount of gas aren't changed."
Halving the pressure on a gas , as long as the temperature of the gas and the voulume of gas aren't changed, does halve its...
What is the formula to calculate gas (air) density at negative pressures, as well as water content ? For instance, a vessel with air with volume of 1 m3, density 1 kg/m3, and water content 10g /m3 get vacuumed from 1BarA to 0.1BarA isothermally.
