I am running an EPS and I have set up a diurnal pattern for the demands. However, when I look at the demands through time, they do not match the base demand times the multiplier.
In some cases the demands are actually lower than the base demand despite a multiplier greater than 1. What is going on?
I tried using this logic: From
"For example, assume the base demand on a given junction is 500gpm, the equivalent hydraulic time step in the calculation options is set to 1 hour, the pattern multiplier for time step 8 is 1.0 and for time step 9 is 1.945, and the Start Time field would be 8 am (assuming the simulation was started at 12 am). The total calculated demand at the junction shown for time step 8 will be (500 * 1) + (500 * 1.945) / 2 = 736.25."
But that didn't give me the correct demand either:
TImestep 9 hr
[.57gpm(1.9)+.57gpm(1.1)]/2=.855gpm but the model shows 1.01gpm at 9 hours.
Please help me understand.
