Two engines A and B have their sources at 400 K and 350 K and sinks at 350 K and 300 K respectively. Which engine is more efficient and by how much ?

Text Solution

AI Generated Solution

To determine which engine is more efficient and by how much, we will calculate the efficiency of both engines A and B using the formula for efficiency in a heat engine: \[ \eta = 1 - \frac{T_2}{T_1} \] where \( T_1 \) is the temperature of the heat source and \( T_2 \) is the temperature of the heat sink. ...
