A 36" concrete culvert is usually submerged on both ends during storm events. The culvert runs under a roadway and is 60 ft long. What is the flow rate with a 6", 18", and 30" difference in water level between the inlet and outlet? Assume a Ke of 0.5 and a Kc of 0.0237.
Stage 1: Using = 0 0237 select the ridged metal pipe outline in course plan
Stage 2: Then draw a line associating the distance across (36 inches) and the length of the course (60 feet) indicated in the bend = 0.5
Stage 3: Then draw a line associating the head (0 5 feet) and it ought to match with the point 0 Extend subject to decide the release
Note: point 0 ought to contain all the three lines contacting (first 1ine, turning line and 2. Compete)
Consequently, the release of the course is Similarly figure for other head
