CIRCULATION MEASUREMENT

By:

Eng. Motasem M. Abushaban.

Eng. Fedaa M. Fayyad.

PURPOSE:

To study some of the famous instruments used in

flow measurements.

п‚ў

The measurement of water flow rate is definitely an

significant topic inside the study of fluid aspect.

There are many tools used in movement

measurements such as:

o Venturi

o Hole plate

u Variable area meter

DESCRIPTION OF DEVICE

Water Movement Measuring Equipment is designed like a

free-standing apparatus for use around the Hydraulics

Table, although it could possibly be used in conjunction with a

low pressure water supply controlled by a valve and a

release to drain. Water gets into the equipment

through the lower left-hand end and goes horizontally

through a sudden enhancement into a clear

venturi meter, and in to an orifice plate, a 90Вє knee

changes the flow direction to vertical and links to a

changing area movement meter, the second bend passes the circulation

into

a

The stationary head at various items in the movement path might be measured on the manometer -panel. The water movement through the equipment is controlled by the delivery control device of the Hydraulics Bench as well as the flow price may be proved by using the volumetric measuring fish tank of the Hydraulics Bench.

Procedure:

1 . Prepare the instruments such that the water passes Sudden Growth, thenVenturi colocar, Orifice dish, Elbow, and ultimately Rotameter.

( Position the Water Flow Testing Apparatus within the horizontal functioning surface with the Hydraulics Bench )

installment payments on your Switch the pump about, allow the normal water to enter the flow way of measuring instruments, that are connected to Manometers tubes.

(Ensure that there are simply no air pockets trapped inside the manometer tubes, if necessary open up the supply valve until normal water spills out from the top of the manometer tubes so the water eliminates out all air bubbles)

Procedure: (cont. )

3. Close the device and allow the level to support with no movement when the height of the water in each manometer conduit should be level with the the top of air vent out (Check for horizontal surface).

4. Control the movement valve to have different blood pressure measurements of the mind in manometers and the related flow in the volume container. 5. Record the effects.

6. Estimate the head loss from the manometer readings as well as the flow and Cd. (some calculations will need Graph)
