A 39.0%/61.0% by volume propane/n-butane mixture is cooled from 291°C to 115°C. Assume ideal behavior.
a) What is the average molar mass of the mixture?
b) What is the change in specific enthalpy of pure propane from 291°C to 115°C?
c) What is the change in specific enthalpy of pure n-butane from 291°C to 115°C?
d) What is the change in specific enthalpy of the mixture from 291°C to 115°C?
e) What is the change in enthalpy of the mixture from 291°C to 115°C in kJ/kg?
This is a very complex exercise... the procedure is showed, you only need to change the fractions and the temperature limits:
