A stream of moist air (mass flow rate = 10.1 kg/s) with humidity ratio of 0.01 $\frac{kg}{kg dry air}$mixes with a second stream of superheated water vapour flowing at 0.1kg/s.Assumping proper and uniform mixing with no condensation, the humidity ratio of the final stream $\left (\frac{kg}{kg dry air} \right )$ is __________________
