Flow experiment
This page documents the flow experiment in the 3rd year labs. It is used as one of the experiments for the Process Dynamics (CPN 321) component of Laboratory (CLB 321). The sections below lists the equipment currently on the rig, and links to software/manuals concerned with the setup.
Hardware
Experimental setup
The experiment consists of feed tank, from which water is pumped to two cascading tanks. Water flows, due to gravity, from these tanks (through valves) and finally into a collection tank. Water can then be pumped back from the collection tank to the feed tank.
Instruments/Devices
The following instruments and devices are fitted onto the flow experiment;
| Instrument/Device | Signal/Connection | Notes |
|---|---|---|
| 2x Pumps | Operated via NI DAQ | |
| 1x Rotameter | Manual reading | |
| 3x Pressure transmitters | 4-20mA / Connected to NI DAQ | In top tank; range: 0-1bar, Manual |
| In lower tank; range: 0-2.5bar. | ||
| In collection tank; currently not working. | ||
| National Instruments DAQ | USB connection to PC |
Software
The National Instruments DAQ is used to interface to the instruments and to LabView for data-logging. A LabView .vi file is used to operate the experiment. The currently used .vi files as well as previously used files can be found here.
