An infinite plate is moved over a second plate on a layer of liquid as shown. For small gapwidth, d, we assume a linear velocity distribution in the liquid. The liquid kinematic viscosity is0.00739 cm²/s and its density is 880 kg/m³. Determine the shear stress on the upper plate, inN/m?.yU = 0.3 m/sd = 0.3 mm

The velocity distribution of air between two parallel plates is linear. The top plate is moving with a velocity of 5.8 m/s and the distance between two plates is 0.1 cm.

A cube of side (a) and mass (M) is initially sitting fully submerged at the bottom of a container filled with a liquid of kinematic viscosity v and density p. The container has a square cross-section of side (a+a/5) and the cube is sitting right at the middle of the container base. (a) A force (F) starts pulling the cube up at a constant velocity (U). Develop an expression for the force in terms of (U, M. a. g, p and v). You may assume that the velocity in the gap between the cube's sides and the container walls is linear. The expression for (F) is to be valid as long as the cube remains submerged. (b) After the cube reaches the water surface, it continues to be pulled up by the same force. Develop a differential equation for the variation with time of the fraction of the cube that is submerged in water.
