In an engine working on Dual cycle, the temperature and pressure at

In an engine working on Dual cycle, the temperature and pressure at the beginning of the cycle are 90C and 1 bar respectively. The compression ratio is 9. The maximum pressure is limited to 68 bar and total heat supplied per kg of air is 1750 kJ. Determine : (i) Pressure and temperatures at all salient points (ii) Air standard efficiency (iii) Mean effective pressure.
