Document Summary
Due date: january 27th 2017, 16:00 pm (or during tutorial: the velocity distribution for water (20 c) near a wall is given by , where and is the distance from the wall in . Determine the shear stress in the water at : a liquid flows between parallel walls as shown below. The velocity distribution near the lower wall is given in the following table. If the dynamic viscosity of the liquid is. Also, where will the minimum shear stress occur? y (mm) u (m/s) 2. 98: calculate the maximum capillary rise of water between two vertical glass plates spaced apart. The surface tension is and the angle is negligible: the surface tension of a liquid is being measured with a ring as shown (side view). The ring has an outside diameter of and an inside diameter of . The force required to pull the ring from the liquid is the weight corresponding to the weight of a mass of .
