Problem 11 on Dual cycle, IC engine, Air standard cycle

For engine working on Dual cycle, Compression ratio= 10, maximum pressure =70 bar, Heat supplied =1681kJ/kg,
At the commencement of compression,
pressure =1 bar
temperature =100°C
Find the pressure and temperature at various salient points and the cycle efficiency
Cp= 1.004 kJ/kgK, Cv= 0.717 kJ/kgK
