I AM SORRY BUT, YOU HAVE SOME INCORRECT INFO HERE. YOUR PHASE DIAGRAM showed that Liquid for (lowP, highT) that is wrong. It should be VAPOR, not LIQUID. please stop teaching wrong things. thanks!

Small correction:

while obtaining dryness factor u have mistakenly taken Mf in the numerator which is the mass of the liquid nt the vapor.

@flyfangirl. A subtle mistake should not call for that rather harsh comment. Everybody makes mistakes.

Hey guys
Be aware that @ 20:00, x=Mg/(Mf + Mg). It's not Mf/( Mf + Mg) (as in the lecture) because Mf stand for the mass of liquid and Mg stands for the mass of vapour.
