outlet 6. The flow of fluid is in the z direction in ducts of triangular cross section and length L as shown in the figure. The velocity in z direction is a function both x and y coordinates and two dimensional representation of one of the duct is shown in (b). (a) y y=H Your friend has obtained the following velocity distribution for laminar flow of a Newtonian fluid in one of the ducts without considering the gravitational force. P(z = 0) - P(z=L) vz(x, y) (y H)(3x2 - y2) 4uLH = y=-v3x y = V3 Verify if she has done this correctly or not. You can write the governing equation directly from the generalized momentum balance equation. Clearly mention the assumptions. 6 Marks (b)
