Tanks With Connecting Conduit Angular Natural Frequency Equations and Calculator

ωn = [ 9 ( 1 + S1 / S2 ) / ( h ( i + S1/S2 + i ( S1/So ) ] (1/2)

Where:

g = Gravity 32.2 ft / sec2
S1 = Area (Cross Sectional) of Tank 1 (ft2),
S2 = Area (Cross Sectional) of Tank 2 (ft2),
So = Area (Cross Sectional) of Conduit (ft2),
h = Height / Depth ( ft ),
i = Distance Between Tanks (ft),
ωn = Angular Natural Frequency ( rad/sec or Hz)

1 rad/sec = 1/( 2π ) Hz
