CORRECT Answers
, what pressure will a scuba cylinder with a rated working 5000 psig (345 bar)
pressure of 3000 psi (207 bar) be exposed to during a
hydrostatic test?
Which principle represents one basis for the hydrostatic permanent expansion
testing of scuba cylinders?
if a visual cylinder inspection reveals corrosion inside a tumbling
scuba cylinder, it may require cleaning by a process
called
which of the following is considered proper care of a preventing moisture from entering the cylinder
scuba cylinder?
two cylinder valves in common use today are the k-valve and din valve
which valve is an example of a special scuba valve that is y valve
required for certain types of specialty diving such as
deep diving with a single cylinder?
which internal valve designs are available in the first stage piston; diaphragm
of scuba regulators?
which valve is unaffected by cylinder air pressure with balanced
regard to the force needed to operate the valve?
which regulator second stage design uses air pressure pilot
rather than mechanical leverage to open the main valve?
in the event of a regulator first stage malfunction, which upstream
type of valve design would be likely to eliminate air flow
to the diver?
when considering a regulator for purchase or use, an high; low
important point to remember is that certain regulators
may not be capable of delivering ____ flow rates at ____
cylinder pressure during an air sharing emergency
which diving instrument incorporates a Bourdon tube cylinder pressure gauges
mechanism?
two benefits derived from using an electronic dive accurate monitoring of ascent rate and, if executing a multi-level diving profile,
computer are avoidance of the maximum time/depth penalty
