This makes the overall reduction 21331. The flood discharge sluicing gate is only opened when the overfall dam cannot meet flood discharge requirement. Adjust the control valve to produce various water depths upstream of the gate and repeat the measurements.

INTRODUCTION A gate valve which is also known as a sluice valve is a valve which opens up by lifting a round or rectangular gate. CHALLENGES IN A TIME OF CHANGE Additional work to provide the fundamental frequency of the gate has been carried out using the finite element method. Sluice Gate in Half-Meter Flume.

So why in the event you deprive your nails of the mystical makeover. The sprocket and chain assembly have a 2671 reduction ratio 12 teeth on the input sprocket 32 teeth on the output sprocket. Try this standout glitter design with a unicorn horn accent nail.

V 2 C d 2gy 1. Therefore the overflow capacity of discharge through gate opening is calculated according to the flow rate of the opening. C-28 Plate C-12 Embedded Anchorage Horizontally and Vertically Framed Miter Gates.

They have three main parts. C d C c 1 C c y 2 y 1 12. Indicatingtheir spacingtheseare theholesusedfor mountingthis.

This factors assume a proper lubrication on stem threads if a poor maintenance is predicted multiply this factors by 115 to 13. The frequency has been determined as approximately 6 Hertz. Manometers for Half-Meter Flume.

Kindly guide me about its flexiure and shear design. Slide 17 of 22. Using the formula below the force on the slide plate can be determined.

Its function is to support the gate and allow it to slide up and down while achieving a watertight seal. Cast iron sluice gate. The relevant seismic loads utilised in the design have been calculated using the methodology proposed by C.

EXAMPLE Sluice gate A sluice gate controls flow in open channels. V 2 Q A 2 Q b z 2. Neglecting bottom friction and atmos-pheric pressure decide the velocities 8 5 and 8 6 and the horizontal force re-quired to hold the gate if D 56 m D 61 m and L5 m.

The moveable part of the sluice gate. Finally we can solve the above equation for Q to find the flowrate through the sluice gate. I want to have your expert advices about a sluice gate design.

Considering a vertical sluice gate in a horizontal smooth rectangular channel the upstream and downstream water depths are respectively 51 and 045 m. A b V1t L CalculationsFor each water depth used determine the flowrate under the sluice gate by using the continuity equation Q QA11Vbz1V. Drive Mechanism This is the mechanism that drives the gate.
