PRESSURE CHANGE MEASUREMENT TESTING METHOD I

A pressure change measurement test performed at a pressure above atmospheric pressure is also referred to as a:

• pressure hold test
• Pressure decay test.
• pressure loss test,
• Any of the above.

Gage pressure plus barometric pressure is:

• absolute pressure,
• Atmospheric pressure.
• Differential pressure.
• Partial pressure.

Standard atmospheric or barometric pressure at sea level is equivalent to:

• 29.96 in. Hg.
• 14.7 psia.
• 760 mmHg.
• All of the above.

A pressure of 66 psig, in terms of absolute pressure at sea level and standard temperature, would be about:

• 96 psia,
• 80.7 psia.
• 51.3 psia.
• 36 psia,

When reading an ordinary pressure gage, the value indicated will be the:

• Partial pressure.
• Incremental pressure.
• Gage pressure.
• Absolute pressure.

A pressure change measurement test of a very large volume structure, such as a nuclear containment system, is usually referred to as a:

• Leakage rate test.
• Verification test.
• Mass flow test.
• Structural integrity test.

Which of the following gases is most practical as the pressurizing medium for a pressure change measurement test?

• Argon.
• Hydrogen.
• Air.
• All of the above.

Surface thermometers for a pressure change measurement test may be held on the test surface with:

• Tape.
• Magnets.
• Coupling adhesive.
• any of the above,

The Pascal (Pa) is the:

• Minimum size volume required for the test.
• Basic unit of mass flow.
• International System of Units (SI) unit of pressure.
• Metric equivalent of standard barometric pressure.

As the elevation above sea level increases, the barometric pressure:

• Decreases.
• Remains the same.
• Increases.
• None of the above.
