An air-standard dual cycle has a compression ratio of 9. At the beginning of compression, p1=100kPa, T1=300K, and V1=14L. The heat addition is 22.7 kJ, with one half added at constant volume and one half added at constant pressure. Determine,
- the temps at the end of each heat addition (K)
- net work of cycle per unit mass (kJ/kg)
- thermal efficiency
- mean effective pressure (kPa)
