Propylene (C3H6) is burned with 50 percent excess air during a combustion process. Assuming complete combustion and a total pressure of 105 kPa, determine the temperature at which the water vapor in the products will start condensing.

3. A rear mounted air-cooled SI engine has 6 cylinders, 3.375 in x 2.6 in bore and stroke respectively, acompression ratio of 8 and developed 80 BHP at 4400 rpm. It was noted that brake thermal efficiency is26 %, volumetric efficiency is 74 % and mechanical efficiency is 71 %. For the ideal cycle, conditions atthe start of compression are 14.7 psia, 140 o F.Calculate a) Percent clearance, b) P, T at the end of compression, c) Brake engine efficiency, d) massflow rate of air, e) torque (lb-ft), f) AF with Q hv = 19100 BTU/lb fuel

If the range of the aircraft needs to be increased to 8000km from 6000km what changes to the engine would you consider to be appropriate?

Part (a)  Find the efficiency of an ideal engine operating between these reservoirs. Remember the efficiency is unit-less, therefore so should your number be as well. ( Party a was incorrect can you try again )  Part (d)  What if the actual work done (more realistically) is W = 290 J during a single cycle; what is the efficiency of this engine if the energy input is the same (again, the number should be unit-less)?  Part (e)  What is equation for the new power output per cycle (in Watts) of this new (and more realistic) engine?
