Hydrostatic testing is performed by filling the piping system with water to the specified test pressure. The test pressure is usually 1.25 to 1.5 times the design pressure. The piping being tested is isolated and filled with water to the test pressure. All joints, both welded and mechanical, ...
The equivalent conclusion when injecting cold water (rather than production testing) implies a preference for injection tests instead of fall-off tests. Underestimating or overestimating the production or injection history for a test (or not including it at all) will result in a deviation from the...
The best way to efficiently clean outdoor surfaces is with a pressure washer, a blaster that uses less water to do its work than a garden hose and nozzle.
Explorer Jacques Piccard and U.S. Navy Lt. Don Walsh, are the first people to reach Challenger Deep after a five-hour descent in the Trieste submersible, setting a new record in underwater exploration. They spent approximately 20 minutes on the ocean floor. March 26, 2012 James Cameron make...

Large differences could indicate faulty flow sensor readings due to factors such as water vapor condensation, buildup of secretions, calibration drift, and integrator drift and should be investigated. Signal Calibration All monitoring or testing instruments require calibration for maintenance of accuracy ...
Acoustic dipole radiation may be found when a simple source is vibrating close to a pressure-release wall, such as the free-water surface, where the simple source produces an out-of-phase image on the other side of the wall. The source and image produce dipole radiation in the fluid half...
