Nature of Flow

1) Allow the water to fill the equipment and adjust the flow rate to the lowest possible value.

2) Adjust the flow rate of the dye solution so that its flow rate is the same as the velocity of water.

3) Measure the volumetric flow rate using a measuring vessel and a stop watch.

4) Increase the flow rate of water in small increments and repeat the above steps.

5) From the highest flow rate decrease the flow rate in small decrements, and repeat the above steps.
