Compute the Second-Law efficiency of the Co-generation system.

Solution

The 2nd Law Efficiency is the best measure of the performance of a process that produces or consumes work.

There is no widely accepted definition for the 2nd Law Efficiency of processes that do not produce or consume work, such as heat exchangers.

Second law efficiency for the following cogeneration system is given by,
