A stream of moist air (mass flow rate = 10.1 kg/s) with humidity ratio of 0.01 kg/kg dry air mixes with a second stream of superheated water vapour flowing at 0.1 kg/s. Assuming proper and uniform mixing with no condensation, the humidity ratio of the final stream in (kg/kg dry air) is ______.

1. 0.02 kg/kg dry air
2. 0.01 kg/kg dry air
3. 0.03 kg/kg dry air
4. 0.5 kg/kg dry air

Correct Option: A

ω_new =	m₁ω₁ + m₂ω₂
	m₁ + m₂

⇒	0.1 × 10.1 × + .1 × 1	= 0.02kg/kg dry air
	10.1 + .1
