The following data were obtained in a test on a combined
separating and throttling calorimeter:

Pressure of steam sample = 15 bar , pressure of steam at
exit = 1 bar, temperature of steam at the exit = 150°C , discharge from separating
calorimeter = 0.5 kg / min , discharge from throttling calorimeter = 10 kg /
min .

Determine the dryness fraction of the sample steam.
