Question

Показания сухого и влажного термометров у психометра совпадают и равны 20°C. Найдите относительную влажность воздуха, используя эти показатели.

Answer 1

Если tсух =tвл, то влажность воздуха φ=100%.
Если пользоваться психрометрической таблицей, то на пересечении строки    t сух=20°  и столбца разности tсух-tвл=0° находим 100%.

Answer 2

Calculation of Relative Humidity

To calculate the relative humidity using the readings from a dry and wet bulb thermometer, we can use a psychrometric chart or an online calculator. However, since we have the temperature readings from the dry and wet bulb thermometers, we can use a simplified formula to estimate the relative humidity.

The simplified formula to calculate relative humidity is as follows:

Relative Humidity = (e / E) * 100

Where: - e is the vapor pressure of the air at the wet bulb temperature - E is the saturation vapor pressure of the air at the dry bulb temperature

To find the vapor pressure at the wet bulb temperature, we can use a table or equation that relates temperature and vapor pressure. Similarly, we can find the saturation vapor pressure at the dry bulb temperature.

Unfortunately, the search results provided do not include the necessary information to directly calculate the relative humidity using the given temperature readings. The snippets provided do not contain the specific information needed to determine the vapor pressure or saturation vapor pressure at the given temperatures.

To accurately calculate the relative humidity, we would need the specific values for the vapor pressure and saturation vapor pressure at the given temperatures. Without this information, it is not possible to provide an accurate calculation of the relative humidity.

If you have access to additional information, such as the specific vapor pressure or saturation vapor pressure values at the given temperatures, please provide them, and I will be happy to assist you further.
