Unformatted text preview: Determine the pressure difference between the blood in the aneurysm and that in the artery. Assume the flow is steady and inviscid. (Use ρ water = 999 Kg/m 3 ) 4. The velocity components for steady flow through the nozzle shown in Fig. 4 are ± = − ² ³ ℓ ⁄ and ´ = ² [1 + ( µ ℓ ⁄ )] , where ² and ℓ are constants. Determine the pressure gradient along the yaxis at point (2) when the fluid is water with ² = 1 m s ⁄ and ℓ = 0.1 m . Neglect viscous effects and use the Euler quation ∇¶ = −· ¸ − ¹ º , where gradient ∇ = » »³ ¼̂ + » »µ ½̂ , ¸ = ¸ ³ ¼̂ + ¸ µ ½̂ is the flow acceleration, and ¹ = −¹½̂ is the gravity. (Use = 999 Kg/m 3 for water) Fig. 3 Fig. 4...
