Fluid flow through a cone equation ?

Click For Summary
Designing an automotive scoop involves understanding the relationship between pressure, velocity, and area, encapsulated in the formula ρVA = constant, where ρ is density, V is flow velocity, and A is cross-sectional area. For deeper insights, "Fundamentals of Aerodynamics" by John D. Anderson is recommended, particularly Chapter 10, which covers flows through nozzles and diffusers. One participant offers to provide a more detailed explanation over the weekend if no one else responds. The discussion highlights the importance of foundational aerodynamics in automotive design. Overall, the exchange emphasizes the need for accurate calculations in creating effective automotive scoops.

I'm in the process of designing a scoop used for automotive purposes. Anybody know some formulas pertaining to pressure, velocity and area dealing with scoops (Funnels, cones, etc)? Thanks for the help! Joe

The basic formula is:

ρ V A = constant

Where ρ is density, V is velocity of the flow, and A is the cross-sectional area.

"Fundamentals of Aerodynamics" by John D. Anderson provides a very in-depth look at flows through nozzles, diffusers and wind tunnels in Chapter 10, if you need more information (it's way more than I can easily go through here)

EDIT: On second thought, I could go through it... I just don't have time until the weekend. If no one else can fill you in before then, I'll write it up. PM me if I forget, please.

Hey, my library has a copy of the book reserved for me! Thank you for your help and willingness to do more. Off to communications class, Joe
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
