What is steam quality x?

Quality x is the mass fraction of vapor in a saturated mixture (x=0: all liquid, x=1: all vapor). h = h_f + x·h_fg, s = s_f + x·s_fg. Turbine exit quality should be x > 0.85 to limit blade erosion.

What are key steam table values to remember?

Atmospheric: 100°C, 1.013 bar, h_f=419, h_g=2676, h_fg=2257 kJ/kg. At 15 bar (design pressure): T_sat=198°C, h_g=2791 kJ/kg. Triple point: 0.006 bar, 0.01°C.

How do I interpolate between steam table values?

Linear interpolation: h(T) = h₁ + (T-T₁)/(T₂-T₁) × (h₂-h₁). For superheated steam, bilinear interpolation in T and P is needed. Use Mollier h-s diagram for quick turbine analysis.
