Water tunnels are ideal for studying flow patterns for hydrodynamic effects. The functionality of the University of Texas-Pan American water tunnel was limited by not being able to measure forces and moments corresponding to flow patterns. This report delivers an experimental set-up for calibrating the velocity of the water and development of a load measuring system to relate simultaneous visual investigation. An in-depth parts breakdown of the SST-model pump and the dye injection system for flow visualization will be reviewed. Few balances have been made for water tunnels due to small and difficult to measure flow-induced forces. The motive is to interpret the coincident load measurement to the observed flow behavior. The UTPA aerodynamic laboratory has developed a multi-component strain-gauge force balance measurement system for its water tunnel. This setup, in its entirety, is able to relate the velocity of the flow to the measured forces and visual flow patterns.
