📚 Introduction to Hydraulic Modeling Tutorial
Mark Wilson, the founder of Akimoto, introduces a tutorial series that complements the EP Annette user's manual, specifically focusing on section 2.7 which deals with running a single period analysis. The tutorial guides viewers through the process of testing their network model by running it and checking for successful execution. It also touches on troubleshooting in case of errors.
📊 Viewing Results Graphically and Tabularly
After a successful run, the tutorial explains how to view the results of the hydraulic modeling in both graphical and tabular formats. It describes how to change the display settings in the map view to visualize pressure and flow at nodes and links, using color coding and legends for easy interpretation. The video also mentions how to manipulate these legends and how to switch between different views for a comprehensive analysis.
🔍 Analyzing Data with Queries and Filters
The script continues with instructions on how to analyze the model's results in a tabular format by selecting specific columns and using queries to filter the data. This allows for a detailed examination of nodes and links, including demand, head pressure, and quality. The tutorial points out the absence of initial quality settings and how to interpret negative flow values, which indicate flow in the opposite direction of the digitized pipe.
🚀 Preparing for Extended Period Analysis
Towards the end of the tutorial, Mark Wilson mentions the 'graph' button, which will be useful in the next video when an extended period analysis is conducted. He encourages viewers to subscribe to the channel, like the video, and visit the Akimoto website for further assistance with their modeling efforts, wishing them good luck in their modeling endeavors.

Transcripts
hello folks my name is Mark Wilson and
I'm the founder of Akimoto
where we inspire confidence and
hydraulic modeling this is another
tutorial in a series that goes along
with the EP annette user's manual this
one will correspond with user's manual
section 2.7 running a single period
analysis so now that we've built our
network hopefully we've got enough data
in there and settings that it will run
so we can test that out by clicking on
the Run button and luckily everything is
good if not it would let us know and we
can troubleshoot it but we're gonna just
run with it with our successful run here
and check out the results ok so how do
we look at results we can do it
graphically or tabular Lee over here in
our browser in the map view we can
change our note display we can look at
pressure you notice that when we do that
the nodes get colored and we get a
legend up over here we can also do the
same thing with links we'll look at flow
and get a legend up egg over here we can
double click on these legends to make
them disappear we can also make them
reappear by going here in our view node
view legends link if we want to look at
our results tabular Lee all we have to
do is click the table button and then we
choose whether we want to look at nodes
or links we're going to look at links
first there we go
there's all of our nodes with associated
demand head pressure and quality we're
now in equality because we didn't set up
any initial quality settings or data
let's just look at links real quick and
you can take her around with what gets
what
shows up in the grid by choosing columns
and then you can also do a query to
limit the results thereby they call it a
filter okay we're just gonna look at all
the links and here we go we see
something interesting here though a
couple of these links have a negative
flow what does that mean that just means
that the flow is going opposite to the
direction we digitized that pipe so
that's all the negative flow number
means we have a graph button here but
that won't be useful until we run an
extended period analysis which we'll do
in the next video so that's all for now
go ahead and subscribe to the channel if
you haven't already please like this
video if you thought it was beneficial
and visit us on our website if you'd
like some help with your modeling
efforts otherwise good luck in your
modeling
