The red dot moves with the phase velocity, and the green dots propagate with the group velocity. In this deep water case, the phase velocity is twice the Wikipedia. Velocity is crucial in physics. But the term is often used interchangeably with speed. Let�s clear this confusion once and for all.� Speed vs Velocity. This is another comparison that leaves many scratching their heads. People often use the term velocity and speed interchangeably, but they both have very distinct qualities. Let us examine the equation of speed. There�s a striking similarity between the equation of speed and velocity.

I am designing a drainage system down the side of an extremely steep embankment, where there was a slope failure due Average Velocity Numericals Worksheets to a leaking block unit catch basin. When I run the analysis through Stormcad, I get the average velocity, velocity in and velocity out.

I understand the velocity in is at the upstream end of the pipe, just downstream of the structure, so is the velocity out the downstream velocity just upstream of the structure? The average velocity is not even near either the velocity in or out.

Can anyone shed some light on whether I should be focusing on the average or velocity out? The more complicated answer probably lies in your Hydraulic Grade Line. If you're using a fairly modern version of StormCAD it will identify locations for hydraulic jumps, which will drastically change the velocities in pipes.

Pull up a profile and look at the HGL, see if it does a funny hop in the middle. Then pull up the help file and see Upstream And Downstream Meaning In Maths Video how "average" is calculated - it may be a weighted average along the pipe instead of just averaging the in and the out, or alternately it may be the normal velocity of a pipe at that slope given that flow, which wouldn't necessarily have any correlation to the in or out velocities in a steep, gradually varied flow situation.

But the simple answer sticks. Look at lowering the slope, and look at alternate pipe materials that are rougher. Something else worth mentioning, is that the very derivation of the Manning's Equation itself which I'm sure StormCAD is based on assumes slopes are flat enough to where you can replace the sin of the bed angle with the tan of the bed angle to make the math easier.

Just an interesting tidbit you might be able to use to win a court case some day. Red Flag This Post Please let us know here why this post is inappropriate. Reasons such as off-topic, Upstream And Downstream Formula Us duplicates, flames, illegal, vulgar, or students posting their homework.
