Equation Derivation

Equation Derivation

(OP)

Hi I was hoping someone could tell me where this equation was derived from,

dP=2*A*pi*Hz

where,

dP= Change in pressure
A: Amplitude
Hz: Frequency

RE: Equation Derivation

A is the peak pressure amplitute
2*pi*HZ = rotational velocity = omega
pressure rate of change = dP/dt = A*omega = A*2*pi*Hz

Imagine a disk of radius A spinning at rotational speed omega.  The radius rate of change is A*omega.

Ted thank you. There is another potential question but I will think about it a little further before I ask.

Thank you once again.
