Reduce the continuity equation for 2D unsteady compressible ow to the one for 2D incompressible ow using the transformation: = t, = x, = Z y ( t,x,y ) d y, (1) and redening the y-component of velocity appropriately. Hint : use the conection operator in your considerations. Problem 9. Consider uid occupying a half-space. At its free surface there are a constant pressure p and a constant shear stress T applied. Determine how much time it takes for the velocity at depth z to take its half-value of the velocity at the free surface. Calculate the value for water and the depth of 100 m. Give your physical interpretation of the result....
