Question

За температури +10 абсолютна вологість повітря становить 3 г/м3 визначте його відносну вологість

Answer 1

1г/м³ - 100%
3г/м³ - Х %
Х = 3× 100 ÷  1
Х = 33,1
      

Answer 2

Relative Humidity Calculation

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 actual amount of water vapor in the air. - Saturation Vapor Pressure is the maximum amount of water vapor that the air can hold at a given temperature.

Calculation Steps

1. Calculate Saturation Vapor Pressure: - Saturation vapor pressure can be calculated using the formula: SVP = 6.11 × 10^(7.5T / (237.7 + T)) where T is the temperature in degrees Celsius.

- Given the temperature is 10°C, we can calculate the saturation vapor pressure: SVP = 6.11 × 10^(7.5*10 / (237.7 + 10))

2. Calculate Actual Vapor Pressure: - Actual vapor pressure can be calculated using the formula: AVP = Absolute Humidity × 6.25 where Absolute Humidity is the mass of water vapor per unit volume of air.

- Given the absolute humidity is 3 g/m^3, we can calculate the actual vapor pressure: AVP = 3 × 6.25

3. Calculate Relative Humidity: - Now, we can use the calculated values to find the relative humidity: Relative Humidity = (AVP / SVP) × 100%

Result

By following these steps, we can calculate the relative humidity based on the given temperature and absolute humidity.
