By deductive problem-solving, determine the cycle efficiency, annual operating cost, and total life cycle cost of an actual diesel cycle. The specific volume at state point 3, v[3], is specified. At a comp. ratio of 10 and isentropic efficiency of 85% v[3] = 0.1337 [m^3/kg]. Use these inputs to perform the hand calculation. Tip: use property relationships to find u[3] then, you can find q in from the conservation of energy from 2 to 3. Explain how to find the best compression ratio and isentropic efficiency for this diesel engine. The inputs to solve are given: C_uf-7 [$/gal] rho_f=0.81[kg/liter] LHV=43200 (kJ/kg] OT=4000 [hr/yr] T(1)-27 [K]+273 [K] P[1]=110 [kPa] omega-2000 [1/min] Displ-0.015 Im^31 CC_r=200 e_r=1.8 CC eta=200 e_eta-1.7 n=15 [yr] i=0.10 "Price per unit volume of fuel" "Density of light diesel Table A-27 Cengel*+++" "Lower heating value Table A-27 Cengel*+++* "Operating time each year based on owner profile" "Temperature of air before compression" "Pressure of air before compression" "Average engine speed" "Displacement volume of engine" "Cost coefficient for compression ratio from parameter opt."
