velocity at the frictional base of the chute. Importantly, those flows can reach steady fully developed states for a range of slopes. Johnson et al. (1990) considered such flow regimes to be governed by both frictional and collisional interactions between the particles. The frictional stresses were considered to be rate independent.

The design of each spiral chute is based upon product specification. The Smooth-Flo Chute, manufactured exclusively by Horn, has no cross seams or ridges to impede product flow. The constant velocity design ensures that the product acceleration is controlled, virtually eliminating product degradation at decline and transfer.

where V is the volume and t is the elapsed time. The SI unit for flow rate is m 3 /s, but a number of other units for Q are in common use. For example, the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min). Note that a liter (L) is 1/1000 of a cubic meter or 1000 cubic centimeters (10-3 m 3 or 10 3 cm 3).In this text we shall use whatever metric units are most ...

More### Open channel spillway - Wikipedia

Chute spillway. Chute spillways carry supercritical flow through the steep slope of an open channel. There are four main components of a chute spillway: The elements of a spillway are the inlet, the vertical curve section (ogee curve), the steep-sloped channel and the outlet. In order to avoid a hydraulic jump, the slope of the spillway must be steep enough for the flow to remain supercritical.

More### Spiral Flow - an overview ScienceDirect Topics

Oct 11, 1994 Note that because the vertical velocity is constant in the geostrophic core region as a result of Eq. (10.163), the vertical velocity in Eq. (10.183) is maintained throughout the core region. Thus, the spiral in the Ekman layer creates a vertical flow that begins with zero at the bottom, and gradually reaches the value of V, given by Eq. (10.183) at the edge of the layer.

A free or potential vortex is a flow with circular paths around a central point such that the velocity distribution still satisfies the irrotational condition (i.e. the fluid particles do not themselves rotate but instead simply move on a circular path). See figure 2. Figure 2: Potential vortex with flow in circular patterns around the center.
