Pneumatic System Angular Natural Frequency Equations and Calculator

ωn = [ ( 2 g ) / S ] (1/2)

T = 2π ( S / ( 2 g ) )(1/2)

Where:

g = Gravity 32.2 ft / sec2
S = Height (linear) of Fluid Column from Bottom ( ft ),
ωn = Angular Natural Frequency ( rad/sec or Hz)
T = Time (sec)

1 rad/sec = 1/( 2π ) Hz
