CHAPTER 10 MOVEMENT OF SEDIMENT BY WATER FLOWS
when the ratio of sediment density to fluid density is very large, as with quartz sand in a wind tunnel, sediment particles are entrained impulsively by the flow at middling to steep take-off angles and move downstream in long arching trajectories little affected by the fluid …

Sand Casting Defects | Informational Encyclopedia
Follows are the some defects and their detail. 1 : Blow Hole. It is smooth depression on the external surface of the casting object. It is also termed as sand blow. 2 : Mismatch or Mold shift. When bottom and top mold plates are mismatched with each other, it causes mold shift defect in the work piece.

the fluid. (b) Water percolates downwards through a sand filter of thickness 15 mm, consisting of sand grains of effective diameter 0.3 mm and void fraction 0.45. The depth of the effectively stagnant clear water above the filter is 20 mm and the pressure at the base of the filter is atmospheric. Calculate the volumetric flow rate per m2 of filter.
Why is desert sand not used for construction?
Beach sand (sold as play sand) has a superior outcome in concrete surface restoration based upon my experience and experimentation in Missouri, US. Choose a sand which is pre washed, or wash it, and sieve it with a fine screen even it comes as pre-screened. This sand is rounded like a desert sand, but perhaps the comparison ends there.
On the generation of surface waves by shear flows ...
A mechanism for the generation of surface waves by a parallel shear flow U (y) is developed on the basis of the inviscid Orr-Sommerfeld equation.It is found that the rate at which energy is transferred to a wave of speed c is proportional to the profile curvature - U "(y) at that elevation where U = c.The result is applied to the generation of deep-water gravity waves by wind.

The method of conformal transformation is used to investigate the steady streaming generated by an oscillatory viscous flow over a wavy wall. By assuming that the amplitude of the wall is much smaller than the Stokes layer thickness, the equations are linearized and solved for large and small values of the parameter kR.This parameter is the ratio of the amplitude of oscillation of a fluid ...
