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;

== 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 [ftp://ragnarok.up.ac.za/publicftp/3rd_year_lab/flow_experiment/software here].
