All,
I am tasked with taking a water model, performing hydrant flow tests, and calibrating said model. I am looking for help in how to define the demands for the various buildings within. Without further ado...
1) It seems to me that the best option is through assigning residential demand to the nearest pipe. I created Thiessen Polygons and, uponvisual inspection, these are simply too inaccurate in the distal regions of the network. I then transitioned to using the load builder to assign homes to the nearest pipe. For model pipe data, I am prompted to enter a method for load assignment. The options are: "equal distribution, distance weighted, closest node, farthest node". Our goal for a worst case scenario is to assign all usage to the dwonstream node, but this doesn't appear to be an option. Which of the available four options would be best?
Coupled with the above question, I am also prompted to choose a polyline distribution for the billing meter layer, with the following options: "equal distribution, proportional distribution". I'm really not sure what the choice even means. What is a polyline distribution?\
2) My last question is a little more broad-viewed. In all, we have geocoded data for 5 different customer types: residential, commercial, industrial, government, and hospital. My thoughts are to assign:
residential usage by an average household demand
commercial usage by square footage
industrial the same as commercial
government will be case-by-case
hospital by number of beds
Does this seem like a logical, efficient way to accurately assign the various demands? Are there sample projects/designs available as examples?
Thanks for any help you may provide,
Marshall
