Problem 3: Express t for a liquid that has a velocity in 3D. Define in the cartesian co-ordinates t both as momentum flux and as stress. Example: 1. Twa. shear stress from force in y-direction on the area perpendicular to x-direction b. y momentum flux transferring in x direction
Problem 4: (a)Solve the following ordinary differential equation with lo,u(y)= A the given boundary conditions: luy=0) = u(y=hl=0 (b) The velocity profile of fluid in between two plates is given by: um Calculate the force being applied on an area of length L, in the direction of the flow and length Ly into the plane ---.[1-672)]
