A Newtonian fluid with a density of 60 lbm/ft³, viscosity of 0.206x10³ lbm/ft•s, and kinematic viscosity of 0.343x10-$ ft?/s undergoes steady shear between a horizontal fixed lower plate (y = 0) and a moving horizontal upper plate (y = 0.03 in). The upper plate is moving in the positive x-direction with a velocity of 3 ft/s, and the area of the upper plate in contact with the fluid is 0.1 ft?. Assume isothermal, incompressible flow. (a) Determine the shear stress exerted on the fluid under these conditions. (b) Calculate the force of the upper plate on the fluid.

Back HW#2 QUESTION1/60pts] A fluid of viscosity u flows in the horizontal cylinder (radius R) shown in the figure under a constant pressure gradient dP/dx. The inner core of the cylinder is filled with a porous material. The flow in this porous region is slow and assumed to be a plug-type flow such that the velocity is constant and everywhere the same inside the porous region. Denote this velocity by Uo. The flow in the open (non-porous) region is steady, Newtonian, incompressible and axisymmetric. It will be assumed that only the axial (x) component of the velocity is non-zero. Flow Open flow T&R Porous media flow R N.B. All your answers must be expressed in terms of µ, U₁, a, R and dP/dx. (a) Use the continuity and Navier-Stokes equations to determine the expression of the velocity in the open region. (b) What is the expression of the average velocity in the open region? (c) Is the assumption of a linear velocity profile in the open region acceptable when this region Tuatifi 1:
