WebThe relationship between the 15-min flow rate and the full hourly volume is given by the peak hour factor, defined in Part A of this chapter (see below). Whether the design hour was measured, established from the analysis of peaking patterns, or based on modeled demand, the peak-hour factor (PHF) is applied to determine design hour flow rates.
WebFor example, students in this study who reported an “aversion to public speaking” as the main deterrent to participation were 5.91 times more likely to report “smaller class size or smaller group activities” as the main factor that would make participation easier for them (95% CI 2.67–13.85, P <0.001). tire size for 2010 chevy hhrWebThe value 484 in the peak-flow equation (see below) from the NRCS Unit Hydrograph is defined as the peak rate factor (PRF).
