A Study on Sloshing Frequencies of Liquid-Tank System

Liquid storage tanks are used to store of liquids. During earthquake activity the liquid exerts impulsive and convective pressures (sloshing) on the walls and bottom of tank. In the present paper, experimental and analytical study is taken up to obtain sloshing frequency of liquid contained in rectangular calculating of circular frequencies fluid in rectangular container. Analytical results of first natural frequency are compared with experiment.
