A laboratory study models the flow around the pier of an off-shore wind turbine with a scaled model of Lr = 20. Determine the model velocity (VM) past the pier, if the water travels with V = 1.3 km/h past the prototype pier. You can assume that water with the same fluid properties is used in both model and prototype with density of Pw = 999 kg/m³ and dynamic viscosity of nw = 0.001 Pa · s. HINT: the flow around the pier is described by the Reynolds number. VM m/s (Provide your answer to 3 decimal places) A laboratory study models the flow around the pier of an off-shore wind turbine with a scaled model of Lr = 20.
