An Internal Combustion Engine has intake air at 350K and a pressure of 1.2 bar. Volume at Bottom dead center is 600cm3. Compression ratio is 9.5. Temperature at state 3 is 2800K. Approximately the engine processes with an otto cycle.

Determine:

A) thermal efficiency
B) net power output if the number of revolutions of the engine is 3600 per minute
C) mean effective pressure
