I'm trying to determine the circular mode frequency for an open-ended pipe using the following equation and could use some clarification:(adsbygoogle = window.adsbygoogle || []).push({});

f = (t/(2*d^2))*SQRT(E/density)

f - frequency

E - modulus of elasticity

d - mean diameter

t - wall thickness

My first question is; do I need to multiply the values inside theSQRTby gravity (386.4 in/sec2) in order to get the correct units for this equation?

Also, is the frequency noted here (f) referring toradian per secondand will I need to divide it by2*piin order to convert it tocycles per second?

Any help would be greatly appreciated. Thanks!
