EXPERIMENT NO. 4
VOLUME FLOW RATE MEASUREMENT BASED ON A ROTAMETER,
A WATER LEVEL INDICATOR, A WATER METER AND
A V-NOTCH VOLUMETRIC FLOW.

I.INTRODUCTION
The experiment covers the comparison among the four flow measuring instruments Rotameter, Water Level Indicator, Water Meter and V-notch). The experiment will discuss how each of the measuring devices works and how to use it.

II.OBJECTIVES:
* To gain knowledge of how flow measuring devices work.
* To study the concept behind the instruments.
* To compare the readings of flow measured among the instruments.

III.MATERIALS AND EQUIPMENT:
* Water Pipeline System (mounted with the measuring instruments) * Water

IV.SAFETY PRECAUTION/S:
* Observe the general safety precautions at all times.
* Do not handle the materials and equipment without the necessary PPE (gloves etc).

V.EXPERIMENT PROCEDURE:
1. Measure the height of the water in the reservoir. No water should be flowing out of the V-notch. Record the initial height. 2. Set the water flow by turning the system on. To adjust the flow, turn the valve on to the desired value with respect to the rotameter. (10L/min, 15 L/min, 20L/min, 25L/min and 30L/min) 3. The water is now flowing. Record the change in the height of the water in the reservoir. Wait for it to even out. 4. Make sure to pay attention on the water level indicator. Set a time of its reading. Example: at 12 seconds, it reads 2 liters. Then its reading is 2L/12s = 10L/min. Record the reading. 5. As you record readings. Have someone take the...
