The following readings were taken with a separating and throttling calorimeter:

\[ \begin{aligned} \text { Initial pressure } & =12 \mathrm{bar} \\ \text { Final pressure } & =1.2 \mathrm{bar} \\ \text { Water separated } & =2 \mathrm{~kg} \\ \text { Barometer } & =760 \mathrm{~mm} \text { of } \mathrm{Hg} \end{aligned} \]

Steam discharged from throttling calorimeter \(=20.5 \mathrm{~kg}\)

Estimate the quality of steam supplied.
