science contact introduction to the gas laws the flow of gases in leaks helium leak test on heat exchangers leak detection and measuring methods leak detection with tracer gas methods leak test with laser beam literature search ^ welcome to leak detection technology what is pressure? pressure is defined as force per unit surface area. where does this force originate from in a container filled with gas? gas consists of a large number of particles (atoms, molecules) which are permanently in motion. when they collide with a surface, their recoil produces a force. pressure is the sum of these forces produced by particles on unit surface area. the unit, in which the pressure is measured, is the pascal (pa = n/m 2 , newton per square meter). another valid unit of pressure is the bar (1 bar = 10 5 pa). the standard atmospheric pressure (dry air at sea level) is 1.013 bar. this value comes from the older, and no longer used unit the torr (760 torr = 760 mm mercury column). what is vacuum? vacuum is produced by removing gas from a container. it is not possible to remove all the gas from a container by pumping; particles still remain in the container, producing a pressure. zero pressure is therefore not possible in practice. the pressure relative to the absolute vacuum is called the absolute pressure. thus there is still a positive pressure even in a good vacuum. atmospheric pressure is about 1 bar absolute, and manometers which zero at atmospheric pressure and show negative in vacuum, measure a relative pressure against atmospheric pressure. note that the negative values do not represent a negative absolute pressure. a gas having a negative pressure relative to the atmosphere is called vacuum. by definition there are four levels of vacuum, depending on the size of the negative relative pressure: rough vacuum fine vacuum high vacuum ultra-high vaccum 1013 - 1 mbar 1 - 10 -3 mbar 10 -3 - 10 -7 mbar <10 -7 mbar 1.013 x 10 5 - 100 pa 100 - 0.1 pa 0.1 - 10 -5 pa <10 -5 pa composition of air air is a mixture of different gases. more than 99% of air consist of nitrogen and oxygen. the rest are other gases. gas nitrogen oxygen argon carbon dioxide neon helium krypton hydrogen xenon percent 79,119% 21,224% 0,946% ~0,0334% 0,00184% 0,00053% 0,000116% 0,00005% 0,0000088% table 1 what is partial pressure? partial pressure is produced by a single gas in a mixture of gases. the table below shows the percentage composition of air. at a pressure of 1.013 bar the oxygen content is 21.224%, the partial pressure of oxygen in air is = 0.21224 bar or 212.24 mbar. the table can therefore be interpreted for partial pressures of the gas mixture in air gas nitrogen oxygen argon carbon dioxide neon helium krypton hydrogen xenon partial pressure 791.19 mbar 212.24 mbar 9.46 mbar 3.34 x 10 -1 mbar 1.84 x 10 -2 mbar 5.3 x 10 -3 mbar 1.16 x 10 -3 mbar 5.0 x 10 -4 mbar 8.8 x 10 -5 mbar table 2 the table shows the partial pressures of the gases in air in relation to the standard pressure of dry air at sea level = 1013 mbar. dalton's law dalton's law gives the relation between the total pressure of a gas in a container and the partial pressure of its constituents. the sum of all partial pressures in a mixture of gases is equal to the total pressure. note that: the gas mixture in a closed volume does not separate. in an air-to-helium mixture, the helium does not rise to the top of the container even though it is lighter than the other gases. this is because of the thermal speed of the particles there are inter-particle collisions in the gas as well as with the container walls and therefore always a mixing process, called "diffusion" what is gas? gas is a substance, where the particles (molecules and atoms) can freely move. in thermodynamic equilibrium these particles are uniformly distributed in space, so that the pressure, partial pressures and gas composition are the same at all points of the container. a solid is a substance, the particles are fixed in their positions, they can only vibrate and rotate. a liquid is a substance, where particles can freely slide on each other but cannot separate from each other, hindered by intermolecular forces. what is vapour pressure? when the pressure above a liquid is reduced at constant temperature, it evaporates and the resulting gas is called a vapour. this vapour, like other gases, has a pressure called vapour pressure. the vapour can become a liquid again. this is called condensation. all vapours have a saturation pressure which is the pressure of the vapour in equilibrium with its liquid. when the pressure in a system is higher than the saturation pressure, the vapour condenses, causing the pressure to return to the saturation value. vice versa, as long as there is still a liquid in the system, the pressure cannot be reduced (by pumping) lower than the saturation pressure, because the liquid continues to evaporate. in a container, in which a liquid and its vapour are present and the pressure is equal to the saturation vapour pressure, evaporation and condensation occur simultaneously. water and its vapour pressure in vacuum systems need our special attention, because water is always present as humidity in the air and water is difficult to remove from vacuum systems. we call gases vapour, when they can condense at normal temperatures. strictly speaking all gases can condense, it depends only how much the temperature is reduced. vapour pressure of water at different temperatures. temp in c 100 50 25 0 -40 -78,5 -196 pressure in mbar 1010.8 130.3 22.6 7.3 0.13 7.7 x 10 -3 1.3 x 10 -9 table 3 vapour pressure of some liquids at 20° c liquid methyl alcohol ethyl alcohol acetone water tetrachlorcarbon high vacuum-diffusion pump oil pressure in mbar 127.7 58.3 245.8 23.37 121.0 10 -7 bis 10 -9 table 4 what is mean free path? the mean free path (mfp) is the average distance which a molecule of a gas- or vapour travels before it collides with another molecule. at high vacuum, these distances become very large, so the particles collide only with the walls of the vacuum chamber. pressure quantity per cm 3 mfp 1013 mbar 3 x 10 19 6,8 x 10 -5 mm 1 x 10 -3 mbar 3 x 10 13 6,8 cm 1 x 10 -9 mbar 3 x 10 7 6,8 km the mean free path is proportional to the pressure. at atmospheric pressure the particles collide every 10 thausandths of a millimetre, but at a pressure of 10 9 mbar they collide only after 68 km. the following formula gives the mean free path for air at 200c at pressure p mbar. the mean free path for some gases at 20° c and different pressures pressure (in pa) pressure (in mbar) mean free path air argon co 2 hydrogen water vapour helium nitrogen neon oxygen 10 -6 10 -8 km 6,8 7,2 4,5 12,5 4,2 19,6 6,7 14,0 7,2 10 -3 10 -5 m 6,8 7,2 4,5 12,5 4,2 19,6 6,7 14,0 7,2 1 10 -2 mm 6,8 7,2 4,5 12,5 4,2 19,6 6,7 14,0 7,2 10 3 10 μm 6,8 7,2 4,5 12,5 4,2 19,6 6,7 14,0 7,2 10 5 1000 nm 68 72 45 125 42 196 67 140 72 table 5 1 nm [nanometer] = 10 -9 m avogadro's law equal volumes of gases at the same temperature and pressure contain equal numbers of gas molecules. what is a mole? a mole (abbreviated to "mol") is a unit of quantity. the definition is: the weight of each gas in a volume of 22.415 litres (at 0°c and 1,013 bar) is equal to the relative mass of one molecule of this gas. example: 1 mol helium = 22.415 litre has a weight of 4 gm. units of quantity can be expressed in different units: volume v mass m number of particles n amount of substance n if it is a gas: "p·v - value" p·v [v] [m] [n] [n] [p·v] m 3 , l, cm 3 kg, g 1 kmol, mol pa·m 3 = n·m, mbar·l the characterisation of an amount of gas as p x v-value is mostly used in vacuum technology. what is a leak rate? a leak rate is an amount of substance, which passes in a certain time through a leak. as we have seen, there are several units for quantity, so the leak rates can also be expressed in different units. the symbol for the leak rate is "q". normally used are: the volume leak rate q = the mass leak ra
