A very large plate, placed in a gap of fixed two infinite planes, is pulled up with a force F and with a constant speed V as shown in the figure. On the left and right sides of the plate there are two different fluids. The side area of the plate is A and thickness of the plate is 0.1t. Weight of the plate is W. Distance between the left plane and the plate is x. The gap between two infinite plates is h=1.1t. Ratio of viscosities of the fluids is 42 = 4. Determine minimum force that can pull up the plate with constant speed V in terms of V, A, , t and W? Neglect pressure changes and assume viscous flow. F Plate

A Newtonian fluid is flowing in the narrow gap between two infinite parallel horizontal plates due to the movement of the top plate (see the figure below). The top plate is moving at a speed U from left to right, and the bottom plate is stationary. Consider the flow is steady, incompressible, and laminar. The distance between two plate is H, and the gravity acts in negative z-direction (which is perpendicular into the page). There is an applied constant pressure gradient of apJəx in the x-direction. Calculate the velocity and pressure fields. Plot typical velocity profiles in dimensionless form for a pressure gradient value of 0 and -15. In your solution show the conceptual diagram of the problem; write all relevant assumptions and boundary conditions; show the detailed steps of the problem solutions including equations and detailed processing of those equations.

A block of mass m slides on a horizontal rough surface head on into a spring of spring constant k = 730 N/m, as shown in Figure. When the block is x = 0.8 meter away from the spring, it has a velocity v = 4.33 m/s. When the block stops, it has compressed the spring by 6.5 cm. The coefficient of kinetic friction between the block and the surface is 0.1. What is the block's mass m (in kg)? Provide your answer with 2 decimal places. Take g = 9.81 m/s2 V
