C) Use the Clapeyron equation and calculate the enthalpy of R-12 [6 marks] (Data: Psat @ -5°C = 260.96 kPa; Psat @ -15°C = 182.60 kPa; vg @ -10°C = Refrigerant at -10°C 0.07665 m3/kg: V @-10°C = 0.00070 m/kg; R = 0.06876 kJ/kg K] D) Under justified assumptions the Clausius-Clapeyron equation is derived from the Clapeyron equations. Outline two (2) uses of the Clausius-Clapeyron equation [4 marks] i) The normal boiling point (i.e. at 1.0 atm) of Argon is -189.2°C and its latent heat of vaporization is 1.21 kJ/mol. Calculate the boiling point of Argon at 1.5 atm ii) C) Use the Clapeyron equation and calculate the enthalpy of R-12 [6 marks] (Data: Psat @ -5°C = 260.96 kPa; Psat @ -15°C = 182.60 kPa; vg @ -10°C = Refrigerant at -10°C 0.07665 m3/kg: V @-10°C = 0.00070 m/kg; R = 0.06876 kJ/kg K] D) Under justified assumptions the Clausius-Clapeyron equation is derived from the Clapeyron equations.
