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, c_v = 0.172 Btu/(lb . °R), and c_p = 0.240 Btu/(lb . °R), determine

(a) heat transfer per unit mass and work per unit mass for each process, in Btu/lb, and the cycle thermal efficiency.

(b) exergy transfers accompanying heat and work for each process, in Btu/lb. Devise and evaluate an exergetic efficiency for the cycle. Let T₀ = 540°R and p₀ = 14.7 lbf/in.².
