Water flows past a flat plate that is oriented parallel to the flow with an upstream velocity of $0\mathrm{.}7\frac{m}{s}.($a$)$ Determine the approximate location downstream from the leading edge where the boundary layer becomes turbulent. $($b$)$ What is the boundary layer thickness at this location? Assume that the water temperature is $15\mathrm{.}6C.$ Use Approximate Physical Properties of Some Common Liquids $($SI Units$).$
