Efficiency of pumping gasoline in service station

This paper studies a gasoline pumping system and evaluates the efficiency of pumping gasoline in service station. The primary motivation of the study is to determine how to improve the efficiency of pumping gasoline in service station. An experimental test rig is setup. After evaluating the efficiency of the pump under different conditions, it was found that the performance is quite different when pumping different medium, which is not match with the pump manufacturer's catalog. And it provides us a guidance to choose the operational parameters of pumps. A phenomenon has been observed which result of the appearance of the BEP (best efficiency point) and the proof needs more works.
