The refrigeration coefficient of the installation is the ratio of the amount of heat taken per cycle from the refrigerating chamber to the operation of external forces:
Vaporization is the process of the transition of a substance from a liquid state to a gaseous state.
The temperature (point) of boiling is called the temperature of the liquid at which the pressure of its saturated vapor is equal to or exceeds the external pressure.
The vapor is called unsaturated (unsaturated) if its pressure is less than the saturated vapor pressure pn at a given temperature.
The isotherm of steam is the curve of the dependence of the vapor pressure on its specific volume at a constant temperature.
The critical temperature is the temperature at which the difference in the specific volumes of saturated vapor and liquid becomes zero.
Absolute humidity of air is the mass of water vapor contained in 1 m3 of air under given conditions.
Relative air humidity refers to the ratio of absolute humidity to the amount of water vapor that is necessary to saturate 1 m3 of air at a given temperature.
The dew point is the temperature at which water vapor, which does not saturate the air, becomes saturating. Knowing the temperature of the air and determining the dew point, calculate the humidity of the air.
The coefficient of surface tension (or surface tension) of a fluid is a quantity determined by the work necessary for an isothermal increase in the surface area of ​​a liquid by one unit:
Deformation of a solid body is called changing its size and volume, which is usually accompanied by a change in the shape of the body.
Elasticity is the property of bodies to restore their size, shape and volume after the cessation of the action of external forces that cause deformation.
The force of elasticity (elastic force) is the force that occurs when the body deforms and is directed in the direction opposite to the direction of displacement of body particles during deformation.
