Question

10\text{ MPa}

Pressure, $p$ (MPa)	Temperature, $T$ ( $^\circ$ C)	Enthalpy, $h$ (kJ/kg)	Entropy, $s$ (kJ/kg.K)
10	500	3373.6	6.5965
1	500	3478.4	7.7621

Pressure, $p$	Sat. Temp. $T_{sat}$ ( $^\circ$ C)	$h_f$ (kJ/kg)	$h_g$ (kJ/kg)	$s_f$ (kJ/kg.K)	$s_g$ (kJ/kg.K)
1 MPa	179.91	762.9	2778.1	2.1386	6.5965
20 kPa	60.06	251.38	2609.7	0.8319	7.9085

P_1 = 10\text{ MPa}, T_1 = 500^\circ\text{C} \Rightarrow h_1 = 3373.6, s_1 = 6.5965
