What was the aim of making sluice gate?
What was the aim of making sluice gate?
The purpose of the gate is to force the dissipation of the kinetic energy of the flow, downstream of the sluice gate, between the gate and the weir: i.e. to induce a (fully developed) hydraulic jump between the gate and the weir. The channel between the gate and the weir is horizontal and smooth.
What is the main effect of a sluice gate as a channel control?
Sluice gates are important structures used to manage the condition and volume of flow in small/micro power plants. A channel controlled at its head by a gate is called a sluice, and a sluice gate is a movable gate allowing water to flow under it.
Why the pressure distribution along the surface of the sluice gate is not hydrostatic?
The pressure distribution on the gate cannot he hydrostatic, as the pressure must be atmospheric at both the upstream water level and at tile point where the jet springs clear of the gate.
What is the function of sluice?
Sluice valve: These valves are used to regulate the flow of water in the pipe system by dividing into the number of sections. Check Valve: These valves are used to check the flow of water in reverse direction. These are generally provided on the delivery side of the pump. These valves work automatically.
How does a sluice work?
Sluice boxes are designed to mimic this naturally occurring gravity separation. As water carries gold-laden sediment through the box, small obstructions called riffles block the free flow of material. These tiny flow restrictions form low pressure pockets where the gold collects.
What is the function of sluice valve?
A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.
What do you know about sluice gate?
Sluice gates are one of the most common hydraulic structures used to control or measure the flow in open channels such as controlling water levels and flow rates in rivers and canals. A water channel containing a sluice gate forms a type of lock to manage the water flow and water level.
What happens when the gate opening is greater than the critical depth?
If the gate opening is equal or greater than the critical water depth, no hydraulic jump would occur, and the gate will not able to regulate the flow in that case (Yen et al.
When the fluid is at rest then?
∵ the fluid is in rest i.e. the velocity gradient is zero, therefore no shear stress/force will be acting and no external force is acting on it, the only force present is due to gravity (Fg) and pressure of the fluid (Fp) i.e. normal force only.
