    A vertical circular cylinder holds 1 cm of liquid water and 100 cm of vapour.
    If P = 200 kPa, the quality is nearest to _____.
    1)1.02%
    2) 10.7%
    3) 40.6%
    4) 80.3%
    Answer is 2). Why? i cant seems to work out the answer.
    From Steam table, at P=200kPa, (Specfic volume) vf= 0.001061, vg= 0.88578
