    What is "shake down", "self limiting stress" and "rache

    I am new to piping engineering and need some help from the experts in understanding some terminology/concepts(see below). 1)what is shake down? 2)Explain self limiting stresses and why primary loads are not self limiting? 3)what is ratcheting? Is it the same as cyclic fatigue?

    Do I need to correct NPSHR in pump curve for different S.G.?

    If my NPSHR curve in the pump curve gives me a value of 10 ft (based on water). Do I need to correct it for a lower specific gravity (S.G) if my pumping liquid has a S.G. of .63. Do I simply do the following (see below)===> NPSHR in the pump curve based on water (S.G.=1) is 10ft...

    The pump cavitated, although here was excessive suction head available

    My pump is cavitating even though there is enough NPSHA. What are some possibilities for this anomaly?

    What exactly does a vortex breaker do?

    I understand that a vortex breaker inhibits the suction/draining liquid from forming a vortex but what exactly does a vortex do to a pump? In other words, what is the adverse affects of not having a vortex breaker? will the vortex travel along 20ft of 20" pipe configured with 3 90deg ells?
