The exhaust temperature of a Carnot heat engine is 228 C.
What is the intake temperature if the efficiency of the engine is 18.3%?
I know the formula is efficiency=1-tc/th.
I got 279 and it was wrong.

th=tc/1-%, so how do I work it out?? :confused:

Hello Maria

How did you precisely get to that 279 C??
