Midterm Progress Assessment ECH 3203, Spring 2009 Thursday, March 5 Directions: Two hours. Open book. No notes. Calculator needed. Maximize your score by showing all work. Good luck to you!! Problem #1: A Flow Meter Calculation (30 points) Determine the fowrate through the pipe as shown in the Fgure: Problem #2: (30 points) The exit plane o± a D p = 0 . 20 m diameter pipe is partially blocked by a plate with a hole in it that produces a d h = 0 . 10 m diameter stream as shown in the Fgure. The water velocity in the pipe is parabolic with a centerline velocity o± v c = 0 . 5 m/s and the velocity in the exiting stream is uni±orm.

Unformatted text preview: Gravity and viscous eects are negligible. Determine the orce necessary to hold the plate against the pipe. Problem #3: (No) Flow between Two Plates (40 points) A viscous fuid oF density between two plane walls at an angle fows downwards due to gravity. A net fow oF zero can be maintained by moving the upper plate at a velocity U as shown. Calculate U given that the viscosity is . The plates are separated by a distance H and it is suggested, though not required, that you use the coordinate system ( x, z ) as shown....
