# Please calculate the efficiency of the reversible, ideal gas

### Customer Question

Please calculate the efficiency of the reversible, ideal gas cycle A-B-C-A. A-B is adiabatic, B-C is on the isotherm, C-A is isochoric. Point A: (50 kPa, 25 L, 150 K) Point B: (250 kPa, 5 L, 150 K) Point C: (427.5 kPa, 5L, 257 K)

I am not in a rush but if the answer is satisfactory and the expert is well versed in thermodynamics, I may use Just Answer for additional thermodynamics questions.

Hi,

Just a note that I haven't forgotten. My thermodynamics was just a bit rusty I had refresh it.

I'll send it through tomorrow (about 24hrs from now)

Hello, I'm just checking in.

Expert:  George Sibiya replied 11 months ago.

HI please confirm for me if these are like that in the question

B-C -> isotherm,

C-A -> isochoric

Customer: replied 11 months ago.

Yes

Expert:  George Sibiya replied 11 months ago.

Ok thanks

Any progress?

Expert:  George Sibiya replied 11 months ago.

I have attempted the question a number of times but some things do not seem to add up

By definition isotherm means temperature remains constant which is supposed to be A -> B

and isochoric is constant volume which is supposed to be B -> C

I have something attached and incomplete which I do not trust myself
