An ideal cold air-standard Diesel Cycle operates at steady state. The pressure and temperature at the beginning of the compression process is 70 kPa and 300 K. The pressure and temperature at the end of the heat addition process is 6 MPa is 2000 K. The Cpof air is 1.1kJ/kg. K and k = 1.4. For the cycle:.
(a) Find the p, T (in K) and specific volume (m²/kg) for each state
(b) the heat addition and work done in each process, in kJ/kg.
(c) the compression ratio
(d) the cutoff ratio
