The problem remains non-examinable this year, but should be interesting enough to be part of the main problem sheet now

Also, the boundary layer momentum thickness is now written as delta** instead of theta.

* Flow parameters (Re, Ma etc) come first, then force coefficients * New brief section on building models * Moved flow-parameters-as-force-ratios section to appendix * Overall re-write & strenthening

* New exercise exploring practical implications of having laminar flow in pipes * Expanded/strengthened oil pipeline problem * Kugel fountain exercise de-listed, moved to back (fun not really critical) * One unconvincing theory exercise moved to archive * Wind tunnel design problem also moved to archive (not so well suited to individual coursework)

The chapter is still unsatisfying in my eyes. I would like to see a more systematic method for quantifying pressure difference in pipes (mixing height, expansion/contraction, local losses, and wall friction losses). I would also like to see a good systematic (even if approximate) exploration of the dependency between the main parameters at hand. * Delta p_friction is now uniformly refered to as Delta p_loss * Ditched entrance effects, focus in on fully-developed flow and on methodology * Summary added at end to better picture relevance of chapter in view of the entire course

Basically re-wrote the chapter, even if core content remains same. * Change in structure: first, general equations, then, incompressible equations * (even) more realistic commentary about usefulness + suitability of the equations. Text now explains (but does not show…) that other terms and equations can be used in practice, according to needs * Derivation of Bernoulli from Navier-Stokes moved to appendix.

* Calculation of forces come first. Moments are ditched * Fixed notation of velocity components: either V_x or u, but not u_x * Velocity-field guesses, which are the core method for the problem sheet, are now presented as a special case (just like fluid statics for pressure force calculations). * Brief example added: Couette flow

* Calculation of forces on wall come first. They are actually the most useful equations in the chapter * The derivation of the "grad p = rho g" equation is now done in 3D, in line with the other chapters. I never completely understood the method I used to use (taken from classic textbooks) and suspect it just is worth nothing Part of the new derivation is taken back from chapter 6. * Static fluids are now clearly presented as a special case. This is now also reflected in the problem sheet.

* Major cleanup. The problems that are not clearly about calculating a pressure force on a wall are gone. * Added one problem with non-static pressure distribution and non-flat surface (taken down from problem sheet 11)

* refreshed formula sheet * labeled non-examinable exercises * fixed page layout somewhat
