From this explanation is not clear nonlinearity of the thermal conductivity of the pressure Here is the schedule thermocouple pressure gauge. https://docs.google.com/viewer?a=v&pid = ... ZjhjYWRlMg Left and right line tends to the vertical (ie the thermal conductivity is independent of pressure). "Thermal conductivity decreases with decreasing pressure," starting with some pressure, then it drops to zero and no further changes. I do not understand about what you say ... you bring a graph axis x (division) shelved current thermocouple (in divisions galvanometer), proportional to the temperature junction space (minus the temperature of the day, which is equal to room temperature). Place heated junction ohmic heating with strongly exposed filament current, so the flow of heat from the thermocouple constant ... More explanation needed?
A literary hero, Pudikov also not needed my food plate methodological advice my food plate ... If you can explain my food plate that for such a hero Pudikov my food plate ... first time I hear ...? This is from the 5th volume of War and Peace. my food plate Munin wrote. (It seems, in collaboration with Gorky.) my food plate _________________ my food plate MNF after jogging, standing at the blackboard "Chariton, drunk meth, standing my food plate in front of the women ... and uttered bad words. Thus began a nice summer day." "Every hour the solar system is approaching the forty-three thousand miles to the spheroidal ..."
Perhaps a way out of the superconducting my food plate state with decreasing temperature? A classic - like, no. HTS - and fuck knows, the theory my food plate has not yet been created. Experimentally, like, no. _________________ In mourning for RAS. - Mathematics in physics delivers all understanding. Room temperature - 0.025 eV. Atmospheric pressure -. Visible light - 1.7-3.2 eV.
I do not understand about what you say ... you bring a graph axis x (division) shelved current thermocouple (in divisions galvanometer), proportional to the temperature junction space (minus the temperature of the day, which is equal to room temperature). my food plate Place heated junction ohmic heating with strongly exposed filament current, so the flow of heat from the thermocouple constant ... More explanation needed? You can find this picture (from the book), in which the left and right ends of the graph go vertically. That is how the vacuum air to a certain value, and increase the degree of vacuum after some values do not affect the thermal conductivity of a rarefied environment. This iron experimental fact. (Thermocouple current does not change, it means the filament my food plate temperature, which stands Joule heat does not change with increasing degree of vacuum)
(Thermocouple current does not change, it means the filament temperature, which stands Joule heat does not change with increasing degree of vacuum) So what's the problem then? First (large pressure), the thermal conductivity is not dependent on the concentration of the molecules and hence of the pressure corresponding to values of the order of the mean free path dimensions of the chamber, the bottom (low pressure) - thermocouple temperature increases so that heat radiation is discharged my food plate sufficiently well, this type of heatsink my food plate is also independent concentration. my food plate Further it is necessary to change the sensor and measure the ionization vakuumetroi
Also this type of heat sink is independent of concentration. I wonder if the thermal conductivity depends on the degree of rarefied gas evacuation? Heat transfer mechanism should be dependent (molecule stuck to the thread, then flew away and stuck to the body of the tube). Smaller residual molecules, the less often it occurs and the smaller the thermal conductivity?
But at atmospheric pressure at which to begin the process of pumping the mean free path, if I'm not mistaken, my food plate the order of a millimeter, my food plate and the distance to the walls of the vaccine. chamber of the order of several cm in such concentrations with falling really my food plate becomes smaller molecules transfer energy, but it is carried on, ie, at a greater distance, due to the increasing length of the communication. path to clashes with less energetic molecules and odds. heat conduction is not dependent on the degree of dilution
At these concentrations, with falling really becomes smaller molecules transfer energy, but it is carried on, ie, at a greater distance, due to the increasing length of the communication. my food plate path to clashes with less energetic molecules and odds. heat conduction is not dependent on the degree of dilution is You will explain the independence of thermal conductivity of the pressure when the mean free path smaller than svobdnogo. And what happens when it is more (scheduled thermal conductivity in this case, too, does not change, why)
(Scheduled thermal conductivity in this case, too, does not change, why) I already wrote that in the graph on the x-axis is not the thermal conductivity and the temperature, which does not change because of the radiation (make up the balance equation, the influx of heat constant care of two terms, one proportional my food plate to the first power of the temperature on the coeff. thermal conductivity is proportional to the concentration of both proportional my food plate to the fourth power of the temperature and concentration dependent. At sufficiently low concentrations
