The second law efficiency of a process is defined as:
1
the ratio of the actual exergy intake to perform the given task to minimum exergy intake to perform the same task.
2
input energy of the device to the output energy of the device.
3
output energy of the device to the sum of the output and input energy of the device.
4
the ratio of minimum exergy intake to perform the given task to the actual exergy intake to perform the same task.
