Mf are the moments supplied by the fluid, which are evaluated by integrating the pressure and friction forces over the surfaces of the blades. Concerning the flow model again the technique involving fixed and moving frames of references as outlined in the previous section can be applied (see Fig. 21). The only difference is that now the angular velocity ω of the rotating frame of reference is no longer constant, but varies with the impeller rotation by ω = Dφ/Dt. , paper, fabrics, arteries, . . ).

The velocity v = v(x) of a (one-dimensional) pipe flow is described by the weak formulation: find v = v(x) with v(1) = 4 such that 3 3 v ϕ dx − 2 3 1 3 v ϕ dx = 1 ϕ sin x dx + ϕ(3) 1 for all test functions ϕ. Derive the corresponding differential equation and boundary conditions.

The deformation of a thin plate, which is subjected to a vertical load (see Fig. 13), can under certain conditions also be formulated as a twodimensional problem. The corresponding assumptions are known as Kirchhoff hypotheses: the plate thickness is small compared to the dimensions in the other two spatial directions, the vertical deflection u3 of the midplane and its derivatives are small, the normals to the midplane remain straight and normal to the midplane during the deformation, the stresses normal to the midplane are negligible.
