Hi Jer,
We put spot elevations at the end of every lateral line serving a drip area. I'm not sure why the program would look for the closest spot when calculating loss. Logically, it should be looking at the spot elevation closest to the furthest lateral line termination point (or last emitter really. But I know that we're not there yet.
In the case of B5 the furthest lateral line termination is at the flush valve. There is a spot elevation there. Shouldn't the program be looking for a spot at the valve (shown as 4454.8) and a spot closest to the termination point (shown as 4455.7)? That would be a differential of .9.
Further, if the differential is 0, then the valve schedule needs to show that instead of looking like it just wasn't calculated (which looks the same as a blank).
I'm sure that I'm missing something, so please enlighten me. There were four missing. Please confirm that your response is valid for the other three that are not showing up. If you or Jake want to call me, please do. You both have my number.
Thanks in advance.
