The Measurement of P-, S-, and R-Wave Velocities to Evaluate ...

The traditional P-wave ultrasonic measurement has been used for the condition assessment of general reinforced concrete structures for a long time, but the effects of prestressing applied to concrete structures such as long-span buildings and bridges on ultrasonic pulse velocity have not been studied clearly. Therefore, this study analyzed the statistical distribution of P-wave ultrasonic pulse velocities in reinforced and prestressed concrete slabs of 3000 × 3000 mm with a thickness of 250 mm.

The Best Velocity for Moving Air Through Ducts | Energy Vanguard

Jun 26, 2019 · The first thing to know about the velocity of air moving through ducts is that the slower you get the air moving, the better it is for air flow. That was the main point of my last article. In fact, the title asked the question, "Is Low Velocity Bad for Air Flow in Ducts?” And the answer was that, in terms of air flow, you really can’t get the air moving through the ducts too slowly.
