Consider a two-dimensional flow field described by a potential function v=c+ dr? - ey? where constant c=4m2.s-1, d=3s-1, e=3s-1 and x and y are the horizontal and vertical position coordinates, respectively measured in meters.

a) derive the stream function (\psi) for this flow field.

b) plot streamlines for three iso-values of \psi=1,2,3. from these iso-streamlines, comment on how velocity in this flow field changes with x, y positions.

c)determine pressure gradient at point (1, 1) located within the field if the fluid is assumed to be water. (hint: include effect of gravity acceleration which is 9.81 m. s-2. density of water can be assumed to be 998.2 kg/m3).

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
