Answer to Question #154356 in Molecular Physics | Thermodynamics for Bryan

Question

determine the volume, internal energy, enthalpy, entropy and density of 3kg of steam at a pressure of 5mn/m² and with a temperature of 350°c

Answer 1

Pressure P = 5 MN/m² = 50 Bar

Temperature T = 350 ºC

By using on-line calculator https://www.steamtablesonline.com/steam97web.aspx

Density d = 19.241 kg/m³

Volume V = 0.15591 m³

Specific internal energy u = 2809.43 kJ/kg

Internal energy U = 8428.29 kJ

Specific enthalpy h = 3069.29 kJ/kg

Enthalpy H = 9207.87 kJ

Specific entropy s = 6.451 kJ/kg*K

Entropy S = 19.353 kJ/K
