Question

At the beginning of the compression process of air-standard Diesel cycle operating with a compression ratio of 18, the temperature is 300 K and the pressure is 0.1 MPa.  The cut-off ratio for the cycle is 2 and the mass flow rate in the system is 1900 kg/hr.

Cp=1.006 kJ/kg K

Cv= 0.717 kJ/kg K

1) calculate the pressure after compression in kPa?

2) which formula should be used to determine the work output of the engine?
