How to operate
1. Demonstrate the relationship between pressure and flow rate of flowing gas
(1) Prepare the instrument.
(2) Remove the three U-shaped tubes from the bracket, apply red ink, make sure they are the same height, and then put them back on the bracket.
(3) Disconnect the connecting tube at the inlet end of the flow tube and allow airflow to enter from the inlet end of the flow tube.
(4) Connect an air pump to the outlet end of the flow tube (note: air must be pumped, otherwise the experiment will fail), and turn on the power. (Note: The air volume must be adjusted from small to large, do not start with a large air volume, otherwise it will easily fail.)
(5) Under a certain air flow rate, different liquid level differences in the three U-shaped tubes can be observed.
