11 refer to the following problem statement and array table for an air-standard Diesel cycle. The entropy production during the expansion stroke is most nearly, The compression work per unit mass of working fluid in the cylinder is most nearly, The heat transfer into the cycle during the combustion process per unit mass of working fluid in the cylinder is most nearly,

Solution

9.Entropy change in expansion=S₄-S₃ =0,option b

10.Since it is adiabiatic compression

     E_in=E_out

h₁+W_in=h₂

Win=h₂-h₁=244btu/lbm so option d

11.Constant pressure heat addition therefore,Qin=h3-h2=749.27...Option d
