I'm looking at Hyraflow express to estimate my inlet spacing and I am puzzled about the results: I entered our typical inlet parameter, ran the calc for a known flow like 2 cfs, looked to see where the spread reached half a lane and the results looked ok. What puzzles me is if I adjust the length of the inlet - say double it for a double inlet the spread does not change for a given flow as matter of fact if I change the inlet length to anything it does not change? I put in 100' recalced and no change - this is reducing my confidence

Seems to be working and changing spread as a function of inlet length in 2013...

Right you have it backwards...It is using correct logic at least, for an inlet/spread/bypass calculation.
This has some pretty cool graphics here.. hopefully this will stand up to rigorous testing for accuracy, which I haven't done.
Thanks for straightening me out. make sure I'm clear: when looking at the graphic the flow is into the page? and the reported spread is down stream of the inlet? But in desigh I need to determine flow to give limiting spread upstream, correct?

You determine where you need to take water off the street at locations where you exceed your spread criterion for the Minor Event. It's an iterative process.
