Work Step by Step
$P_{1}=300kPa$
$\upsilon_{1}=0.5\frac{m^3}{kg}$
As $0.001073\frac{m^3}{kg}\lt \upsilon\lt 0.60582\frac{m^3}{kg}$ is a saturated mixture
From table A-5:
$T_{1}=133.52^{\circ}C$
$P_{2}=300kPa$
$x_{2}=1$
$T_{2}=133.52^{\circ}C$
From table A-5:
$\upsilon_{2}=0.60582\frac{m^3}{kg}$
$P_{3}=600kPa$
$\upsilon_{3}=0.60582\frac{m^3}{kg}$
As $\upsilon_{3}\gt \upsilon_{g}$ is a superheated vapor
Interpolating from table A-6:
$T_{3}=517.77^{\circ}C$
