$60\%$ A cubic tank $(0\mathrm{.}5m0\mathrm{.}5m0\mathrm{.}5m)$ and a spherical tank $($diameter $=0\mathrm{.}8m)$ are filled with water.

Conditions in the Cubic tank: $x=0\mathrm{.}7$ and pressure $=10$ bar

Conditions in the Spherical tank: $x=0\mathrm{.}8$ and pressure $=12$ bar Calculate

The mass of liquid and the mass of vapor at each tank $(20\%)$

The total enthalpy at each tank $(20\%)$

The heat required to achieve saturation conditions at each tank $(20\%)$
