`50m^(3)` of saturated vapour is cooled down from `30^(@)C`to `20^(@)C.Find the mass of the water condensed. The absolute humidity of saturated water vapour is `30g m^(-3)`at `30^(@)C`and `16g m^(-3) at 20^(@)C`.

Explanation

To solve the problem of finding the mass of water condensed when 50 m³ of saturated vapor is cooled from 30°C to 20°C, we can follow these steps:

### Step 1: Calculate the mass of water vapor at 30°C
Given that the absolute humidity of saturated water vapor at 30°C is 30 g/m³, we can calculate the total mass of water vapor in 50 m³.

\[ \text{Mass at 30°C} = \text{Absolute Humidity} \times \text{Volume} = 30 \, \text{g/m}^3 \times 50 \, \text{m}^3 = 1500 \, \text{g} \]
