Question details

9. (a) A mixture in an engine cylinder has the following volumetric analysis: 17% 02 15.5% Co, 67.5% N2 Calculate: (i)the analysis by mass (ii) the molecular mass and the gas constant of the mixture (ii) the specific heat capacity at constant pressure and constant volume of the mixture (a) The mixture, which is originally at 950°C expands reversibly according to the law pv125 constant through a volume ratio of 8 to 1 Calculate (i)The final temperature of the mixture (ii) The work done per unit mass of the two mixtures (ii)The heat transfer per unit mass of the mixture (iv)The entropy change per unit mass of the mixture Take the Cpof CO2, N2 and O2 to be 1.230, 1.167 and 1.100 kJ/kg K respectively.
