what is the specific enthalpy of steam at 1000 psia and 560

what is the specific enthalpy of steam at 1000 psia and 560 deg F.

Solution

Given pressure = 1000 psia = 68.94 bar

temperature = 560 F = 293.33 oC

We know that specific enthalpy (h) = h_f + x(h_{fg) ---------------(1)}

From steam tables at 1000 psia and 560 F

hf = 1266.82 kJ/kg

h_fg = 1505.08 kJ/kg

substituting above values in equation 1

we get specific enthalpy h = 2808.31 kJ/kg
