Answer 2

Calculating Absolute and Relative Humidity

Given: - Air temperature = 22°C - Dew point temperature = -15°C

To find: 1. Absolute humidity 2. Relative humidity

Absolute Humidity Calculation

The formula to calculate absolute humidity is: Absolute Humidity = 6.112 * e^((17.67 * Td)/(Td + 243.5)) * (1.01 * T) / (273.15 + T)

Where: - Td = Dew point temperature in °C - T = Air temperature in °C - e = Base of natural logarithm, approximately 2.71828

Substitute the given values: Absolute Humidity = 6.112 * e^((17.67 * (-15))/(-15 + 243.5)) * (1.01 * 22) / (273.15 + 22)

Calculating the absolute humidity using the given formula yields: Absolute Humidity ≈ 4.85 g/m³

Relative Humidity Calculation

The formula to calculate relative humidity is: Relative Humidity = (e / es) * 100

Where: - e = Vapor pressure - es = Saturation vapor pressure

The vapor pressure (e) can be calculated using the formula: e = 6.112 * e^((17.67 * Td)/(Td + 243.5))

The saturation vapor pressure (es) can be calculated using the formula: es = 6.112 * e^((17.67 * T)/(T + 243.5))

Substitute the given values: e = 6.112 * e^((17.67 * (-15))/(-15 + 243.5)) ≈ 0.228 kPa es = 6.112 * e^((17.67 * 22)/(22 + 243.5)) ≈ 2.65 kPa

Now, calculate the relative humidity: Relative Humidity = (0.228 / 2.65) * 100 ≈ 8.6%

Conclusion

- Absolute humidity is approximately 4.85 g/m³. - Relative humidity is approximately 8.6%.
