You are conducting a series of flow experiments in order to investigate flow across a horizontal flat plate. When water at 51.9°C flows across a flat plate, the distance from the front edge of the plate to where the transition from laminar to turbulent flow occurs is determined to be 314mm. 1. What is the bulk velocity of the water flowing over the plate? 2. If the experiment is done with Refrigerant-22 instead of water and the same distance from the edge is measured, what would the bulk velocity be? 3. Compare the velocity and thermal boundary layer thickness at the laminar/turbulent transition point of the two cases above and comment on your finding.
