Part Nbrs. WaG/Cer
Pressure transients with rise rate in excess of 100,000psi per second are very common. For example 50 psi and greater spikes at 1000 Hz. are a rise rate of at least 100K psi/sec. Pressure travels in an average liquid at a mile a second, so it will take 1/1760 secs to pass through a 36" WaveGuard. However some of the transient will travel three times the distance around the balls, and some will go a hundred different distanced paths through them. The parts of the transient will arrive at the other end at different times.
This time lag, spreading the base time, reduces the height of the transient to near nothing.
The volume of liquid between the balls, approx. 30% of the total cylinder volume, has a mass deadening effect and its compressibility also helps.
Three things have caused the disappearance of the high frequency transient disturbances, time lag has spread the base reducing the height, mass has deadened, and the modulus of compressibility has absorbed.
WAVEGUARDS WITH THE CERAMIC BALL PACK ARE FOR HIGH FREQUENCY ATTENUATION.
