Figure Lengend Snippet: ( A ) Multi-lane swimming chamber, modified after . Design modifications included rounded instead of rectangular-shaped raceways (244.0-mm length × 20.9-mm width ×37.3-mm depth) and flow straighteners that were doubled in length (80.0 instead of 40.0 mm). These changes helped (i) reduce the areas of lower flow velocity and (ii) increased flow uniformity. The drawing was created in CAD software and can be downloaded from the . ( B ) Organizational chart of the SCADA system monitoring and regulating water parameters and flow velocity in the swimming chamber. PLC allows temperature and carbon dioxide partial pressure ( p CO 2 ) to be simultaneously checked and adjusted. Water flow can be controlled by two proportional valves (a high- and a low-flow one) that are adjusted according to the set flow velocity.
Article Snippet: The design of the multi-lane swimming chamber was drafted using CAD software (AutoCAD Inventor®, Autodesk Inc, San Rafael, CA, USA), and the individual components were machined from polymethylmethacrylate panels using a computerized numerical control cutting machine (Mazak Integrex J-200, Yamazaki Mazak, Oguchi, Japan).
