In a separating and throttling calorimeter for determining the dryness fraction, steam is throttled from $1.5 \mathrm{MPa}$ to $0.15 \mathrm{MPa}$. The temperature of steam after throttling is $150^{\circ} \mathrm{C}$. The discharge from the separator, which is placed ahead of the throttling device, is $0.2 \mathrm{~kg} /$ minute of water, while the discharge from the calorimeter is $12 \mathrm{~kg} /$ minute. Determine the dryness fraction of the steam entering the separator.
