Abstract
In the previous report, it was experimentally observed that liquid rising could occur in a suction pipeline containing an abrupt enlargement. However, the characteristics of liquid rising in such suction pipelines could not be estimated theoretically. The objective of the present study is to predict the characteristics of liquid rising theoretically. An advanced three dimensional theory based on pressure correct and additional mass has been developed. The experimental investigation of suction pipelines containing an abrupt contraction also has been made. Experimental results gave good agreement with the theoretical analysis.
