ROUND UP TO 4 DECIMAL PLACES. Draw and label the P-V & T-S
diagrams.
An Ideal air standard dual-combustion cycle has a compression
ratio of 15. At the start of the compression process, the air
temperature and pressure are 30°C and 150kPa respectively. Heat
addition takes place until the maximum cycle temperature reaches
1950°C and produces total heat of 1200 kJ/kg. Determine (a)
Temperature, specific volume and Pressure at each state, (b) Net
work output (kJ/kg), and (c) thermal efficiency....
