Please Help!! Integration! Hi!! I'm having a little problem with an exercise and I dunno how to sort it out. Basically what I have is a tube of 5mm ejecting spray fuels. At the exit plane I have positioned lasers to measure the volume flux at different locations, starting from one side of the tube to the other side. The increment for each location was of 0.0254mm. At each location I measured the volume flux, now I have to calculate the total volume flux and I don't know how to do that (I have a basic idea but I'm not quite sure about it). Could you guys help me out here? I've attached a picture illustrating what I have. The spots along the diameter line are the volume flux at each location. http://img88.imageshack.us/img88/2066/jato.jpg [Broken] Thanks!
