Otto, Diesel, and Dual Cycles
Consider a cold air-standard Diesel cycle. Operating data at principal states in the cycle are given in the table below.
The states are numbered as in Fig. 9.5. For k = 1.4, cv = 0.718 kJ/(kg . K), and cp = 1.005 kJ/(kg . K), determine
(a) the heat transfer per unit mass and work per unit mass for each process, in kJ/kg, and the cycle thermal efficiency.
(b) the exergy transfers accompanying heat and work for each process, in kJ/kg. Devise and evaluate an exergetic efficiency for the cycle. Let T0 = 300 K and p0 = 100 kPa.
