INLET TO BE USED - CALTRANS TYPE D1
6in Dia Pipe will Not Produce Bypass Flow
Check Drain Pipe Bypass (Due to Capacity of 6" Dia Orifice):

ANALYSIS ASSUMPTIONS AND LIMITATIONS
1. Analysis based on Type D1 CALTRANS Deck Drain (See CALTRANS Standard Plan B7-6)
Flow Bypassing Grate:
Flow Within Grate Width:
Check Longitudinal Bypass (Due to Legth of Inlet):
OK - Longitudinal Flow Within Grate Length - No Bypass
Type D1 Deck Drain Efficiency =
Inlet Flow Intercept
SUMMARY FOR GUTTER FLOWING FULL
