Water at 20°C is flowing through a 20-cm-square smooth duct at a (turbulent) Reynolds number of 100,000. For a laminar flow element measurement, it is desired to pack the pipe with a honeycomb array of small square passages (see Fig. P6.28 for an example) what passage width h will ensure that the flow in each tube will be laminar (Reynolds number less than 2000)?
