Based on the information given the total efficiency of the process is: 14.4%
Using this formula
Total efficiency =Crude production×Refining× Transportation×Engine efficiency
Where:
Crude production=95.9%
Refining=80.5%
Transportation=93.4%
Engine efficiency=20%
Let pug in the formula
Total efficiency =95.9%×80.5%×93.4%×20%
Total efficiency=14.4%
Inconclusion the total efficiency of the process is: 14.4%
