A diesel cycle with air as the working fluid has a compression ratio of 20. The temperature and pressure in the first process is 20°C, 95kPa and the highest attainable temperature is 1927°C. The air standard assumptions are applicable, both Kinetic and Potential energy are negligible. The mass/mass flow rate is negligible. Use the standard constants for air (Cp, Cy. R, and k). Determine the amount of heat transferred and rejected, the net work and thermal efficiency, and the mean effective pressure.
Two ideal Brayton cycles (see Figure below) have the same inlet temperature and the same maximum temperature of the turbine inlet. Brayton Cycle A has a higher compression ratio than Cycle B. Which of the following statements is true about the cycles? Cycle A has a higher thermal efficiency and Cycle B has a higher work net for a given mass flow rate. Cycle B has a higher thermal efficiency and a higher work net for a given mass flow rate. Since the temperatures are the same the efficiencies and work net are also the same. Cycle A has a higher work net for a given mass flow rate and Cycle B has a higher thermal efficiency. Cycle A has a higher thermal efficiency and a higher work net for a given mass flow rate.
