Question

Относительная влажность в комнате при температуре 16 градусов составляет 65%, как она изменится при понижении температуры воздуха на 4 градуса, если абсолютная влажность останется прежней?

Answer 1

Дано    Ф1=65%     t1=16C    t2=16-4=12C     Ф2- ?

при 16C     pн1=13,6 г/м3
при12С      pн2=10,7 г/м3

Ф=p*100%/pн
Ф2/Ф1=pн1/pн2

Ф2=Ф1*pн1/py2=65*13,6/10,7=82,6%
ΔФ=82,6-65=17,6%

Relative Humidity and Temperature Change

The relative humidity in a room is the amount of moisture present in the air compared to the maximum amount of moisture the air can hold at a given temperature. In this case, the relative humidity in the room is 65% at a temperature of 16 degrees Celsius.

To determine how the relative humidity will change when the air temperature is lowered by 4 degrees Celsius while the absolute humidity remains the same, we need to understand the relationship between temperature and relative humidity.

According to the search results, the relationship between temperature and relative humidity can be calculated using the formula:

RH2 = RH1 x (T2 / T1) where: - RH2 is the new relative humidity - RH1 is the initial relative humidity - T2 is the new temperature - T1 is the initial temperature

Let's apply this formula to the given scenario:

- Initial relative humidity (RH1): 65% - Initial temperature (T1): 16 degrees Celsius - Change in temperature (T2 - T1): -4 degrees Celsius (temperature is lowered by 4 degrees)

Using the formula, we can calculate the new relative humidity (RH2):

RH2 = 65% x (12 / 16) RH2 = 48.75%

Therefore, if the temperature is lowered by 4 degrees Celsius while the absolute humidity remains the same, the relative humidity in the room will decrease to approximately 48.75%.

Please note that this calculation assumes that the absolute humidity remains constant. If there are other factors that affect the moisture content in the air, such as ventilation or changes in the moisture source, the actual change in relative humidity may differ.
