Development of Acoustical Prediction Model for Asphalt
Previous research results have shown that traffic noise is mainly generated from tire/road noise for high velocity vehicles. For traffic noise assessment, the controlling factors for the acoustical properties and the tire/road noise on asphalt pavements are not known very well, such as vehicle categories, tire types and material characteristics

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.
Chapter 3 Time of Concentration and Time of Concentration
(1959) or Linsley et al. (1982). After average velocity is computed using equation 3-4, T t for the channel seg-ment can be estimated using equation 3-1. Reservoirs or lakes Sometimes it is necessary to estimate the velocity of flow through a reservoir or lake at the outlet of a watershed. This travel time is normally very small and can be

Determining the Stability of Asphalt Concrete at Varying
In this study, ultrasound velocity method was used to determine the probable relationship between pulse velocity and the Marshall stability of the asphalt core specimens. For pulse velocity measurement, a pulse velocity device with a digital screen was used. The machine used in the test was suitable for both BS 1881-203 and ASTM C597-02.
