(a)
Interpretation :
Determine the maximum possible thermal efficiency of the plant and minimum rate at which heat must be discarded to the river.
Concept Introduction :
The maximum thermal efficiency of plant is possible if and only if plant considers as a Carnot engine. The thermal efficiency of Carnot engine is
And efficiency also write as
(b)
Interpretation :
Determine the heat is discarded to the river and the temperature rise of the river if it has a flow rate of
Concept Introduction :
The actual thermal efficiency of the plant is calculated as:
Where
And efficiency is
