Hi(adsbygoogle = window.adsbygoogle || []).push({});

Could any one help me with this?

How would i go about calculating the thermal efficiency of a heat engine with four processes?

I am thinking of moddeling it on the Otto or Diesel Cycle.

The data i have is.

Temp @ State/Process 1

Specific Gas Constant

Specific Heat Capacity

and i have

Pressure

Volume

for states one, two, three and four.

How would i got about figuring out the thermal efficiency? do i use a NFEE equation?

Thanks for any help.
