Question

рассчитайте относительную влажность воздуха; если абсолютная влажность составляет 6 г в 1 м3 при температуре + 30

Answer 1

относительная влажность=5г в м3

Answer 2

Calculating Relative Humidity

To calculate the relative humidity, we can use the formula:

Relative Humidity = (Actual Vapor Pressure / Saturation Vapor Pressure) × 100%

Where: - Actual Vapor Pressure is the pressure exerted by water vapor in the air. - Saturation Vapor Pressure is the maximum pressure of water vapor that the air can hold at a given temperature.

Given: - Absolute humidity = 6 g/m³ - Temperature = 30°C

Calculating Saturation Vapor Pressure

First, we need to calculate the saturation vapor pressure at the given temperature using the Clausius-Clapeyron equation:

Saturation Vapor Pressure (SVP) = 6.11 × 10^((7.5 × T) / (237.7 + T))

Where: - T is the temperature in degrees Celsius.

Plugging in the given temperature (30°C) into the equation:

SVP = 6.11 × 10^((7.5 × 30) / (237.7 + 30))

SVP ≈ 4.246 kPa

Calculating Relative Humidity

Now, we can calculate the relative humidity using the formula:

Relative Humidity = (Actual Vapor Pressure / Saturation Vapor Pressure) × 100%

Given that the absolute humidity is 6 g/m³, we can convert this to kPa using the ideal gas law and then use it as the actual vapor pressure in the formula.

I'll calculate the actual vapor pressure and then the relative humidity.
