1. The problem statement, all variables and given/known data https://fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-prn2/p526x296/960031_10201604348407190_1235705166_n.jpg 3. The attempt at a solution Hey! Well, I don't really know where to start, even.. Heck, I think the problem is formulated pretty badly (with width, I assume they mean length of the cylinder?).. Anyway, I think I can solve the problem with the following steps: 1) I can probably assume inviscid flow. 2) I need to figure out the velocity-distribution around the cylinder, and then the pressure distribution. I think I will somehow need to superimpose a vortex and linear-flow? 3) Calculate the difference in pressure between the outside and the inside. 4) Calculate the force on each bolt. My problem is 2: I simply have no clue what to do. Please help?
