A mass of air at 30⁰c can hold 17.117gm/m3 of moisture. The same air temperature has 6.262gm/m.3Calculate the relative humidity

To calculate the relative humidity, we need to compare the actual amount of moisture present in the air (absolute humidity) to the maximum amount of moisture the air can hold at that temperature and pressure.




Given:

  • Absolute humidity at 30⁰C = 6.262 g/m³
  • Maximum moisture holding capacity at 30⁰C = 17.117 g/m³

Relative Humidity can be calculated using the formula:

Relative Humidity = (Actual Absolute Humidity / Maximum Absolute Humidity) * 100%

Plugging in the values:

Relative Humidity = (6.262 g/m³ / 17.117 g/m³) * 100% Relative Humidity = 0.3652 * 100% Relative Humidity ≈ 36.52%

Therefore, the relative humidity at 30⁰C is approximately 36.52%.
