Problem $2(50$ points$)$: In an ideal Diesel cycle, the air is at $80$ kPa and $5C$ at the beginning of

the compression process $($state $1).$ The maximum temperature of the cycle is $1000C.$ The

compression ratio is $7.$ Consider the air standard assumptions.

Part $1)$ Sketch the P$-$v diagram for this cycle.

Part $2)$ In the cycle described above, which intensive property remains constant in the

compression process:

heat addition process:

expansion process $($no heat addition$)$:

heat rejection process:

Part $3)$ Determine the temperature, specific internal energy, and specific enthalpy at the start of

the compression process.

Part $4)$ Determine the temperature, specific internal energy, and specific enthalpy at the end of

the compression process.
