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?
If the temperature inside the engine is 60 °C and the pressure at the start of compression of an ideal air-powered diesel cycle 0.9 is 105 Pa.
