Solution
Inter-cooling in a gas turbine results in an increase in both thermal efficiency and net output.
Here's why:
-
Inter-cooling is a process used in gas turbines to cool the air intake in between stages of compression.
-
By cooling the air, the volume decreases which allows for more air to be taken in during the next stage of compression. This means that more fuel can be burned and more work can be done, increasing the net output.
-
The cooling process also reduces the amount of work the compressor has to do, which increases the thermal efficiency of the turbine.
-
Therefore, inter-cooling in a gas turbine results in an increase in both thermal efficiency and net output.
