Full Solutions please. Thank you!
Dodecane is burned with 50% excess air and with a molar-base combustion efficiency of 90%. The emissions leave the combustion chamber at a total pressure of 100 kPa. a) Calculate the mass-base and molar-base fuel-to-air ratio. (10 pts) b) Calculate the mass-base and molar-base equivalence ratio. (10 pts) c) You should get the same result for the mass-base and molar-base equivalence ratios in part (b). Prove mathematically that it was not a fluke. (10 pts)...

Please answer all PROBLEM 1 A three-litre four-stroke diesel engine develops 12 kW per m3 of free air inducted per minute. The volumetric efficiency is 82 % at 3600 rpm referred to atmospheric condition of 1 bar and 27 oC. A rotary compressor which is mechanically coupled to the engine is used to supercharge the engine. The pressure ratio and the isentropic efficiency of the compressor are 1.6 and 75 % respectively. Calculate the percentage increase in brake power due...
ME 322/51 Problem 2) (20 pts) (No Partial Credits) i. One Kmol of carbon, a 25 C and 1 atm is burned steadily with 1 Kmol of oxygen, O, at the Test 4 same state. The CO formed during the process i...
ME 322/51 Problem 2) (20 pts) (No Partial Credits) i. One Kmol of carbon, a 25 C and 1 atm is burned steadily with 1 Kmol of oxygen, O, at the Test 4 same state. The CO formed during the process is then brought to 25PC and 1 atm. Assuming the combustion is complete; determine (a) the reversible work and (b) the exergy destruction for this process ii. Determine the higher heating value (in kJ/kg-f) for Ethylene gas, C.H, at...
Methane gas is burned with 30 percent excess air. This fuel enters a steady- flow combustor at 0.8 atm and 25oC and is mixed with the air. The products of combustion leave this reacto...
Methane gas is burned with 30 percent excess air. This fuel enters a steady- flow combustor at 0.8 atm and 25oC and is mixed with the air. The products of combustion leave this reactor at 0.8 atm and 1600 K. Determine the equilibrium composition of the products of combustion and the amount of heat released by this combustion in kJ/kmol methane. Use data from the tables CH 25°C CO2, H3O chamber NO. O2 N2 1600 K 30% excess air 25°C...
