The maximum amount of work performed is
![W_{max}=\frac{T_H-T_C}{T_C}Q_C](https://tex.z-dn.net/?f=W_%7Bmax%7D%3D%5Cfrac%7BT_H-T_C%7D%7BT_C%7DQ_C)
Explanation:
The efficiency of a real heat engine is given by the equation:
(1)
where
is the temperature of the cold reservoir
is the temperature of the hot reservoir
However, the efficiency of a real heat engine can be also written as:
![\eta = \frac{W_{max}}{Q_H}](https://tex.z-dn.net/?f=%5Ceta%20%3D%20%5Cfrac%7BW_%7Bmax%7D%7D%7BQ_H%7D)
where
is the maximum work done
is the heat absorbed from the hot reservoir
can be written as
![Q_H=W_{max}+Q_C](https://tex.z-dn.net/?f=Q_H%3DW_%7Bmax%7D%2BQ_C)
where
is the heat released to the cold reservoir
So the previous equation can be also written as
(2)
By combining eq.(1) and (2) we get
![1-\frac{T_C}{T_H}=\frac{W_{max}}{W_{max}+Q}](https://tex.z-dn.net/?f=1-%5Cfrac%7BT_C%7D%7BT_H%7D%3D%5Cfrac%7BW_%7Bmax%7D%7D%7BW_%7Bmax%7D%2BQ%7D)
And re-arranging the equation and solving for
, we find
![W_{max}=\frac{T_H-T_C}{T_C}Q_C](https://tex.z-dn.net/?f=W_%7Bmax%7D%3D%5Cfrac%7BT_H-T_C%7D%7BT_C%7DQ_C)
