Since heated air, especially in cold weather, has a low relative humidity some means of moistening the air of living rooms should be provided.
After the dew point has been obtained, one may compute the relative humidity or degree of saturation of the atmosphere, from the table given below.
For the most healthful conditions the relative humidity should be from 40 per cent.
The latter moves over a printed scale and indicates directly the relative humidity.
Thus, air with a relative humidityof 50% has just half as much water vapor in it as it could hold.
The relative humidity of the air is the ratio between the amount of water vapor which the air contains at any particular time and the total amount which it could contain at the temperature it then has.
Since the amounts of moisture that air will hold depends on its temperature, and as the air is ordinarily only partly saturated, the varying amount of moisture are expressed either as relative humidity and stated in per cent.
At all seasons of the year Simpson found A rise notably with increase of relative humidity.
Gockel found a diminution of ionization with rise of relative humidity.
Observations on the Sonnblick agree with those at low-level stations in showing a diminution of dissipation with increase of relative humidity.
At Karasjok, Simpson found a slight decrease in I- asrelative humidity increased, but no certain change in I+.
For that reason many students of aridity pay little attention to temperature, relative humidity, or winds, and simply measure the evaporation from a free water surface in the locality in question.
Relative humidity At a definite temperature, the atmosphere can hold only a certain amount of water vapor.
Relative humidity is simply the ratio of the actual vapor pressure present in a given space to the vapor pressure when the space is saturated with vapor at the given temperature.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "relative humidity" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
