PROBLEM
Consider a porous sphere sitting in a pool of stagnant Newtonian fluid (with constant viscosity μ). Liquid with constant viscosity μ is forced out radially from the sphere. Your ultimate goal is to find the velocity profile vi(r) of the liquid outside the sphere. The radius of the sphere is given by R. Assume the flow to be steady state; vo-Vo-0; and neglect gravity. Also, the velocity at the sphere surface is given by v(R)-Vo. Assume steady...

Problem 1: A Newtonian fluid is confined between the plate and a fixed surface. If the velocity profile is defined by u =(8y-0.3y) mm/s, where y is in mm, determine the force that must be applied to the plate to cause this motion. The plate has a surface area of 15 (10) mm in contact with the fluid. Use u = 0.482 (10) N.s/m(20 points) (8y-3.3y) du -0 T = Muy 72 (0.482 +5%) (8- 0.64)...

Consider the turbulent flow of air, density 1.2 kg/m3 and kinematic viscosity 1.5x10-5m2/s, through a channel bounded by two infinitely wide parallel plates 0.2 m apart. At a certain downstream location where fully-developed conditions apply, the wall shear stress is measured to be 0.027 N/m2. a. Determine the streamwise mean velocities at locations 0.25 mm and 1 cm from the wall. b. At which of these two locations do you expect to find the larger Reynolds shear stress.
