The steam is generated at 8 bar from water at \(32^{\circ} \mathrm{C}\). Find the heat required to produce \(1 \mathrm{~kg}\) of steam.

(a) When the steam at dryness \(=0.9\).

(b) When the steam is superheated with a temperature \(=300^{\circ} \mathrm{C}\).

Take \(c_{p s}=2.3 \mathrm{~kJ} / \mathrm{kg} . \mathrm{K}\) for superheated steam.
