The compressor and turbine of a simple gas turbine each have isentropic efficiencies of 80%. The compressor ratio is 12. The minimum and maximum temperatures are 290 K and 1400 K, respectively. On the basis of an air-standard analysis, compare the values of (a) the net work per unit mass of air flowing (in kJ/kg), (b) the heat rejected per unit mass of air flowing (kJ/kg), and (c) the thermal efficiency to the same quantities evaluated in an ideal cycle.

Calculate the specific weight of toluene at a place where the acceleration of gravity is 32.2 ft/s^2or 9.81 m/s^2. Express your answer in both lbf/ft^3 and kg/m^3. Repeat this for Mars whre the acceleration due to gravity is 37.5% of that on Earth.
a stream of gas flowing at 15000 scfm contains 20 ppm of toluene. assuming the process operates 8500 hours per year
