Suppose that glycerin is flowing (T = 20C) and that the pressure gradient dp/dx is 1.2 kPa/m.

Question:

Suppose that glycerin is flowing (T = 20°C) and that the pressure gradient dp/dx is –1.2 kPa/m. What are the velocity and shear stress at a distance of 11 mm from the wall if the space B between the walls is 5.0 cm? What are the shear stress and velocity at the wall? The velocity distribution for viscous flow between stationary plates is
