Unformatted text preview: 5. (Condo Effect — 10 pm) A circular cylinder held tangent to a flowing rectangular stream (width to intothepaperanddensiry p)caoses it no deflect (see Figure). Assume that gravity and friction efl'eels are negligible. In order to evaluate the vertical component of the force required to hold the cylinder in place the following questions must be addressed: (a) Choose a control volume and clearly indicate your CV. axes, and all other symboIs that you need to define on the Figure (1:) Determine the velocity of the jet at 2, V2. iii-M) 1w“- 1144 W hMmGiQD ' .fiz1,=P+z-‘5’;+a r“ ‘%*K;9 7/ X23 ?/ (Wfiés) (c) Determine an algebraic expression for the vertical component of the force required to hold the cylinder in place in the terms of the given problem parameters. \me’iam "1:33 2 (4- Mkfiéfhfi) [5] ...
