Being equipped to discuss the problem, and understand the answers.
A. Shaking the pipe generates pressure pulses.
B. How to turn pressure waves instead of reflecting them.
C. Transient dissipation. Acoustic Volumes.
D. Reduce pipe sizes.
E. Diameter changes are points of reflection.
F. Be careful of orifices.
Pressure VELOCITY - 3600mph, goes a mile in a second. Mass flow only 15 mph. How resonant pressure AMPLIFICATION can occur.
The vital importance of LARGE DIAMETER. Why pressure changes must pass into flow - not go passed any attenuator.
Pumps, with one exception, are not the cause of shock, surge or pulsation pressures. HARD arteries and PIPES kill people and pumps.
Gauges are "PRESSURE INDICATORS". That is why the symbol is Pl. They can only indicate dynamic activity, gauges can not measure it.
SUCTION SUPPLY LINE PROBLEMS. When starting flow in a pipe to a pump, and repetitively in the case of a reciprocating machine.
Preventing supply piping from destroying a pump. TWO DO'S TWO DON'TS. Decoupling system response from negative spike excitation.
