An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27°C, and 750 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Considering the constant specific heat at room temperature, then determine the pressure and temperature at the end of the heat- addition process, calculate the net work output, find the thermal efficiency, calculate the mean effective pressure for the cycle, and i) ii) iii) iv) Elusta CC.

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.
