Question
### Flow in a Closed Cavity

Consider steady flow in the closed cavity shown in the figure. The bottom and side walls are fixed, while the top surface slides to the right at speed \( U \). The fluid-filled space is relatively narrow, such that \( H/L \ll 1 \). This allows the flow in the central part of the cavity (away from the end walls) to be fully developed.

#### Diagram Explanation

- **Coordinate System**: The \( y \)-axis is marked vertically, and the \( x \)-axis is marked horizontally. 
- **Flow Description**: The fluid is contained within a rectangular cavity. The height of the cavity is denoted by \( H \) and the length by \( L \).
- **Boundary Conditions**: The top surface moves to the right at speed \( U \), inducing flow within the fluid, while side and bottom walls remain stationary.
  
#### Objective

Determine the fully developed velocity profile, \( v_x(y) \).
