Voorbeelden van chute

• The medium-grained sandstone bodies are probably gully or chute fills, caught on the shelf edge as a current passed overhead.

• It is this portion of the apparatus that enables us to control the state of the particulate material as it enters the chute.

• With dense entry conditions acceleration to the fully developed flow was apparently complete quite near the top of the chute.

• These configurations will be referred to as the smooth chute and the rough chute, respectively.

• These were taken 91.5 cm downstream from the chute entry, with the tip of the probe flush with the surface of the lateral wall.

• In the rough chute the loose entry condition branches for different inclinations lie so close together as to be almost indistinguishable if superimposed.

• This is, perhaps, to be expected in view of the larger resistance t o slip a t the base of the rough chute.

• Angles of wall friction are quoted for both the smooth and the rough chute bases.

• Velocities are high throughout the layer and, in particular, the slip velocity a t the base of the chute is large.

• These probes were also used to measure free-surface velocities along the chute.

• Annular shear cells and inclined chute flows are the two flow geometries most suitable for comparison with theoretical predictions.

• If the gate valve is then opened, the material enters the chute in a dense, slowly moving state.

• For the smooth chute in no case was anything resembling the loose entry branch predicted.

• In our experiments 6 was measured by a clinometer attached to the chute.

• This consists of an upper supply hopper which feeds the chute through a pre-chute chamber.
