DEPARTMENT OF CIVIL ENGINEERING TECHNOLOGY HYDRAULICS & HYDROLOGY LABORATORY TITLE : THE FORCE ON A SLUICE GATE 1.0 OBJECTIVE

To determine the relationship between upstream head and thrust on a sluice gate (undershot weir) for water flowing under the sluice gate.

2.0 LEARNING OUTCOMES At the end of the course, students should be able to apply the knowledge and skills they have learned to: a.

Understand the basic terms and concept of a sluice gate.

b.

Understand on the characteristics of the force on a sluice gate.

3.0 THEORY It can be shown that the resultant force on the gate is given by the equation,

. The gate thrust for a hydrostatic pressure distribution is given by the equation,

where,

is resultant gate thrust (N),

resultant hydrostatic thrust (N),

is volume flowrate (m/s),

gravitational constant (9.81 m/s2),

is breadth of gate (m),

is upstream depth of flow (m) and

is

is density of fluid (kg/m 3), is height of upstream opening (m),

is downstream depth of flow (m).

4.0 EQUIPMENT

1. Self-contained Glass Sided Tilting Flume 2. Adjustable Undershot Weir 3. Instrument Carrier 4. Hook and Point Gauge

5.0 PROCEDURE 1.

Ensure the flume is level, with the downstream tilting overshot weir at the bottom of its travel. Measure and record the actual breadth

(m) of the undershot weir. Install the undershot weir

towards the inlet end of the flume and ensure that it is securely clamped in position. 2.

Adjust the undershot weir to set its bottom edge 20 mm above the bed of the channel.

3.

Introduce water into the flume until

= 200 mm. With

at this position, take readings for

and varying 4.

. Raise the undershot weir in increments of 10 mm, maintaining constant . At each level of the weir, record the values of

Repeat the procedure with a constant flow and

6.0 RESULT AND CALCULATIONS

Weir breadth=………………………mm Table 6.1: The force on the sluice gate

7.0 QUESTIONS 1.

Plot a graph of the ratio

against the ratio

2.

Comment on the graph obtained.

3.

Compare your calculated values for

and comment on any differences.

4.

What is the effect of flowrate on the results obtained?

5. Discuss the results. 6. Give a conclusion for this test.
