Turbulence

2016-12-12 · The stronger the wind speed (generally, a surface wind of 20 knots or higher is required for significant turbulence), the rougher the terrain and the more unstable the air, the greater will be the turbulence. Of these factors that affect the formation of turbulence, stability is the most important.

Flat Feet: Symptoms, Causes, Diagnosis, and Treatment

The wet footprint test is performed by wetting the feet and standing on a smooth, level surface. The thicker the print between the heel and ball of the foot, the flatter the foot. By contrast, a high-arch foot would leave only a narrow print of the outer foot. The shoe inspection test can provide evidence of faulty foot mechanics. If you have flat feet, there will be more wear on the inside of ...

Cliff Mass Weather Blog: Why are our fronts different?

2010-4-7 · Why do we get these showers AFTER the front? Because there is plenty of moisture (not surprising) and the atmosphere is relatively unstable there. The ocean surface is "relatively" warm--roughly 50F year-round off our coast, and the air behind the front (cold or occluded front) is even colder, coming off of Alaska or Siberia.

Minimum Steel Reinforcement in Concrete and Clear …

The minimum amount of steel reinforcement is defined as that for which "peak load at first concrete cracking" and "ultimate load after steel yielding" are equal. In this way, any brittle behavior is avoided as well as any localized failure, if the member is not over-reinforced. In other words, there is a reinforcement percentage range, depending on the size-scale,

Clinkerization

Main factors dictating size of kiln are the retention time (25-30 minutes) of material in kiln, degree of filling (10-17%) and thermal loading of burning zone (2.8-4.8 x 10 6 kcal/h/m 2). Pre-calciner kilns are shortest in length, as 90-95 % calcination is completed outside the kiln.
