    1. The problem statement, all variables and given/known data
    why the fluid need the wall to eliminate the shear stress?

    2. Relevant equations

    3. The attempt at a solution
    is it because if there is no wall to support teh fluid , the fluid would move continously , resulting the shear stress act on water?
