Unformatted text preview: What value would K have to have for the fluid to be incompressible? 4. , For the same velocity field given in Pb 3 determine the total . volume per second of fluid leaving a cube with each edge 2 m , = , =. , = , =. , = =. long with its six faces at x 0 x 2 y 0 y 2 z 0 and z 2 . respectively What is this volume flow rate if the fluid is incompressible? 5. If is a 3D velocity field where is the distance from the origin of the coordinate system and A and n are constants: determine the volume flow rate passing though a sphere of radius r. What value of n would make that volume flow rate independent of r? What values of n would make the volume flow rate increase on bigger and bigger spheres? 6. TBD...
