(b) Find .
(ii) A flat horizontal surface has a small hole at its centre. A circular glass plate of radius is placed symmetrically above the hole with a small gap remaining between the plate and the surface. A liquid enters the gap symmetrically from all sides and after travelling radially through the gap finally exits from the hole. The volume flow rate of the liquid coming out from the hole is (in ).
(a) If the flow speed just inside the circumference of the circular plate is find the speed of flow inside the gap at a distance (see figure) from the centre of the hole.
