Summer d. Fall e. No, the season doesn't matter.Internal combustion engine I hope for a solution and as soon as possible, with thanks and appreciation
- 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?CHOICES: a. 30 deg b. 45 deg c. 67.5 deg d. 22.5 degQ1a.
