(5 ) Safety Vacuum Release System ( SVRS )-The term'safety vacuum release system'means a vacuum release system capable of providing vacuum release at a suction outlet caused by a high vacuum occurrence due to a suction outlet flow blockage.
2.
The losses initially result from impaired heat transfer, corrosion damage ( in particular under-deposit and crevice corrosion ), increased pressure drop, flow blockages, flow redistribution inside components, flow instabilities, induced vibrations ( possibly leading to other problems, e . g ., fatigue ), fretting, premature failure of electrical heating elements, and a large number of other often unanticipated problems.
