WebPeaking Factor - The ratio of peak hourly flow to average daily flow. Rainfall-Induced Infiltration - The short-term increase in infiltration which is the result of a rain event. Rainfall-induced infiltration is a portion of delayed inflow. Wet Weather Flow- The highest daily flow during and immediately after a significant storm event. WebAccordingly, the maximum depth of flow in design shall be limited to 0.8 (80%) of the diameter at ultimate peak flow. Here d is defined as actual depth of flow considering average flow in the pipe and D is full depth of …
WebThe peak hour flow rate is also given in passenger car units/hour. Sometimes these two terms are used interchangeably because they are identical numerically. Peak Hour Factor. The peak hour factor (PHF) is derived from the peak hour volume. It is simply the ratio of the peak hour volume to four times the peak fifteen-minute volume.
