A 450 mm diameter culvert has been designed to convey a discharge of Q = 0.55 m3/s of storm-water under a residential road. The culvert is 37.5 m long and has a slope of 1.3%. The downstream flow depth was obtained as 0.35 m from a hydraulic analysis. You are required to determine:1.1 the head required to convey the discharge through the culvert at full flow conditions;(a) If concrete pipe is used with a Manning’s roughness coefficient of n = 0.0155 with an inlet headwall of socket type. (b) If corrugated steel pipe is used with a Manning’s roughness coefficient n=0.024 with an inlet headwall of square edge design. 1.2 What is the corresponding headwater depth in 1.1 (a) and (b) above?

Question
A 450 mm diameter culvert has been designed to convey a discharge of Q = 0.55 m3
/s of
storm-water under a residential road. The culvert is 37.5 m long and has a slope of 1.3%. The
downstream flow depth was obtained as 0.35 m from a hydraulic analysis. You are required
to determine:
1.1 the head required to convey the discharge through the culvert at full flow conditions;
(a) If concrete pipe is used with a Manning’s roughness coefficient of n = 0.0155 with an
inlet headwall of socket type.
(b) If corrugated steel pipe is used with a Manning’s roughness coefficient n=0.024 with
an inlet headwall of square edge design.
1.2 What is the corresponding headwater depth in 1.1 (a) and (b) above?
