Fluid mechanics - Water flowing through a pipe

[QUOTE="theBEAST, post: 4294199, member: 380493"] [h2]Homework Statement [/h2] [ATTACH=full]159569[/ATTACH] [h2]The Attempt at a Solution[/h2] I am interested in why my method is flawed: [ATTACH=full]159570[/ATTACH] Alright I know how to do this problem. Essentially you solve mass flow rate = rho * double integral of u dA. HOWEVER, I decided to do this differently. I know that I can solve for the average u from the equation mass flow rate = rho * u_avg * A. I also know that the average u is just the integral of u over the integral of 1. I tried this and I get 1.528 m/s which is clearly not one of the answers. Why does my method not work? [/QUOTE]
