A newly purchased sedan car operates on an ideal thermodynamic cycle. The engine has acompression ratio of 10. The ambient air pressure is 1 bar while temperature is 21 ºC. Themaximum temperature in the engine is 1600 K. Draw the ideal power cycle and label it.Utilizing the air-standard assumptions, determine (a) the gas temperature at the exits of thecompression and the expansion processes, (b) the specific works of compression, expansionand net, (c) heat supplied to the engine and (d) the thermal efficiency.
Draw and label the P-V and T-S diagrams. In an ideal Brayton cycle, air enters the compressor section at 14.7 psia and 55°F. The pressure ratio is 12. Turbine inlet condition of 1300°F. Determine the following:a. Work, per unit massb. Heat Rejected, per unit massc. Thermal Efficiency
3. In a gas turbine plant air is compressed from 1.01 bar and 15 °C through a pressure ratio of 5. It is then heated in a combustion chamber at constant pressure to a temperature of 700 °C and expanded to atmospheric pressure in a turbine. The isentropic efficiencies of compression and expansion are respectively 0.8 and 0.85. Calculate (a) the cycle efficiency and (b) the work ratio. Assume that the properties of air do not change with temperature and may be taken as Cp = 1.005 kJ/kg K and y = 1.4.
