The velocity at cross-stream of a turbulent wake is calculated using the formula\(\frac{U_{max}-U}{U_{max}-U_{min}}=b(\frac{y}{b})\) Note:Umax→ Maximum velocity at a particular cross-sectionUmin→ Minimum velocity at a particular cross-sectiony → Distance in the cross-stream direction from the centre line at the cross sectionb → Cross-stream half widthU → Velocity at the distance ‘y’The minimum velocity here corresponds to _____________

• A. Velocities at the edges
• B. Velocities just downstream of the object
• C. Velocities of the surrounding free stream
• D. Velocities at the centreline
