A mixture of gases in a closed system consists of 0.1 kg O, 1 kg CO, and 0.5 kg He. The mixture is maintained at 100kPa and 27°C. Calçulate: (a)

the mass fractions for each component (b) the mole fractions for each component (c) the apparent molar mass (d) the apparent gas constant for the mixture (e) the specific volume of the mixture v, (f) the apparent specific heats (C., C, and k) Consider the flow of these gases through a compressor to 500kPa. Find: the exit temperature if the mixture is compressed isentropically to 500kPa a) the isentropic efficiency and the actual specific work input if the actual exit state is 580K,500kPa
