In a test with a separating and throttling calorimeter, the following observations were made : Water separated \(=2.04 \mathrm{~kg}\)

Steam discharged from throttling calorimeter \(=20.6 \mathrm{~kg}\) at \(150^{\circ} \mathrm{C}\)

Initial pressure of steam \(=12\) bar abs.

Final pressure of steam \(=12.3 \mathrm{~cm}\) of mercury above atmospheric pressure Barometer \(=76 \mathrm{~cm}\) of mercury Calculate the dryness fraction of steam entering the calorimeter.
