The graphs for the data can be found here. Notice the curve behaviour in the range from 1mm-7mm.

Hello blueoak...
Could I ask what you mean by "A clinging nappe has a specific range where it increases flow"? I could not find this range in the document. Also, what do you mean when you say "that limbo area of laminar flow"?
Using the paper I mentioned in my earlier post, I calculated the...
The reason for finding out the flow does not have anything to do with measuring flow of an open channel of water, which is why I'm not using a v-notch.
My application has to do with building water features and I wanted to calculate the minimum req'd flow to create a cascading flow of water...
You're correct... I don't have any doubt that my test data is wrong. However, I thought I'd get at least recognizable results. In any case, I think I will use this journal entry:
"Simple Discharge Relations for Sharp-crested Rectangular Weir and Right-angled Triangular Weir at Low Heads"...
While I try to obtain Cameron Hydraulic Data, could anyone tell me whether or not the tables offered are from experimental results or just values from using an equation?
JStephen, the formulas both work properly at high heads, but differ quite a bit at lower heads.
I'm trying to find tables...
Thanks for the quick reply! I'm using the same Francis formula, but I have a supressed weir, where the width of the weir is the width of channel, so there are no contractions.
The (L-0.2H) you see is for two end contractions, and (L-0.1H) is for one contraction. With zero contractions, the term...
Hey
I'm trying to find a formula that will let me calculate the required flow in a weir for a specified head and length. For example, if I had a weir that was 1 foot long and had a head of 0.2", and I wanted to find the flow.
I have a few problems... first, there seem to be many variations on...
