Consider a cold air-standard Diesel cycle. Operating data at principal states in the cycle are given in the table below.For k=1.4 Cv=0.718kJ/(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 the exergetic efficiency for cycle. Let T(initial)= 300K and p(initial)= 100kPa
State T(K) p(kPa) v(m^3/kg) (specific volume)
