## Homework Statement

Two heat engines operating on Carnot cycles are arranged in series. The first engine A receives heat at 927 deg C and rejects heat to a reservoir at a temperature T. The second engine B receives the heat rejected by the first engine, and in turn rejects heat to a reservoir at 27 deg C.

## Homework Equations

Calculate the temperature T, in deg C, for the situation where:

a)The work outputs of the two engines are equal

b)The effeciencies of the two engines are equal

## The Attempt at a Solution

I have completely lost the plot with this and really need help!
