the velocity profile for a slow-moving (laminar flow) glycerin is 1.2kg/ms, flow between two stationary parallel plates is given, in m/s by: u=C*(y/h - y^2/h^2) where h, the distance between the two plates, is 8 cm. A pitot tube measures the centerline velocity to be 1.5 m/s. find the dimensions and magnitude of C and calculate the shear stress on each wall and at the channel centerline
