Enthalpy - Some Basic Applications

Some Basic Applications

The points a through h in Fig.2 play a role in the discussion in this Section.

a T = 300 K, p = 1 bar, s = 6.85 kg/(kgK), h = 461 kJ/kg;

b T = 380 K, p = 2 bar, s = 6.85 kg/(kgK), h = 530 kJ/kg;

c T = 300 K, p = 200 bar, s = 5.16 kg/(kgK), h = 430 kJ/kg;

d T = 270 K, p = 1 bar, s = 6.79 kg/(kgK), h = 430 kJ/kg;

e T = 108 K, p = 13 bar, s = 3.55 kg/(kgK), h = 100 kJ/kg (saturated liquid at 13 bar);

f T = 77.2 K, p = 1 bar, s = 3.75 kg/(kgK), h = 100 kJ/kg;

g T = 77.2 K, p = 1 bar, s = 2.83 kg/(kgK), h = 28 kJ/kg (saturated liquid at 1 bar);

h T = 77.2 K, p = 1 bar, s = 5.41 kg/(kgK), h =230 kJ/kg (saturated gas at 1 bar);
