50 m 3 of saturated vapor is cooled down from 30°C to 20°C. Find the mass of the water condensed. The absolute humidity of saturated water vapor is 30 g m –3 at 30°C and 16 g m –3 at 20°C.

Question

Philoid · Accepted Answer

Given

Initial temperature =30

Final temperature =20

Absolute humidity of saturated water vapor at 30= 30 g m^–3

This means 1m³ of air contains 30g of water vapor at 30.

So, amount of water vapor in 50m³ of air at 30=5030=1500g

Absolute humidity of saturated water vapor at 20= 16 g m^–3

So, amount of water vapor in 50m³ of air at 20=5016=800g

Amount water vapor condensed from 30 to 20 = 1500-800

= 700g

The mass of the water condensed is 700g.
