.
Explanation:
Fluid given Ammonia.
Inlet 1:-
Temperature 
= 
.
Pressure 
= 10 bar.
Exit 2:-
Pressure 
= 1 bar.
Solution:-
Answer:
22.86%
Explanation:
To get the overall efficiency of the process, we simply get the product of the given efficiencies.
Therefore, overall efficiency of the process=Crude production efficiency* Transportation efficiency* Refining efficiency* Distribution of gasoline efficiency* Engine efficiency efficiency
Overall efficiency=0.93*0.92*0.94*0.97*0.293*100%=22.85798714
%
Approximately, the overall efficiency of the process is 22.86%
