Question

Температура воздуха в комнате 30 градусов цельсия, относительная влажность 60%, как найти абсолютную владность?

Answer 1

Ρ = φ ρo

ρ= 0,60*30,4 г/м³

Answer 2

Calculating Absolute Humidity

To calculate the absolute humidity, you can use the following formula:

Absolute Humidity (AH) = (Relative Humidity (RH) * Saturation Vapor Pressure) / 100

Where: - Relative Humidity (RH) is given as 60%. - Saturation Vapor Pressure is the maximum amount of water vapor that can exist in the air at a given temperature. It can be calculated using the Clausius-Clapeyron equation or obtained from a table.

Using the Clausius-Clapeyron Equation

The Clausius-Clapeyron equation is used to calculate the saturation vapor pressure at a given temperature. The equation is given by:

ln(P) = -L/R * (1/T - 1/T0)

Where: - P is the saturation vapor pressure. - L is the latent heat of vaporization. - R is the gas constant. - T is the temperature in Kelvin. - T0 is the reference temperature in Kelvin.

By rearranging the equation and solving for P, you can find the saturation vapor pressure at the given temperature.

Calculation Example

Let's assume the temperature in the room is 30 degrees Celsius. To calculate the absolute humidity, we can use the Clausius-Clapeyron equation to find the saturation vapor pressure at this temperature and then use it in the absolute humidity formula.

Step 1: Convert Temperature to Kelvin - T = 30°C + 273.15 = 303.15 K

Step 2: Calculate Saturation Vapor Pressure - Using the Clausius-Clapeyron equation and the appropriate constants, we can calculate the saturation vapor pressure at 30°C.

Step 3: Calculate Absolute Humidity - Using the obtained saturation vapor pressure and the given relative humidity of 60%, we can calculate the absolute humidity using the formula mentioned earlier.

By following these steps, you can find the absolute humidity at the given temperature and relative humidity.
