Question
Design a box culvert to carry a design discharge of 600 cfs. The culvert invert elevation is 2100 feet, and the allowable headwater elevation is 2114 feet. The paved roadway is 500 feet long and overtops at an elevation of 2115 feet. The culvert length is 200 feet with a slope of 1%. The following tailwater elevations apply up to the maximum discharge of 1000 cfs:
Discharge (cfs) 200.00 400.00 600.00 800.00 1000.0
Tailwater, ft 2101.4 2102.6 2103.1 2103.8 2104.1
Prepare a performance curve of the culvert design by hand and compare with the results of HY8. Also, use HY8 to prepare a performance curve if the slope is 0.5%.

- Fluid Mechanics Hw Please label all answersarrow_forwardA grass-lined roadside channel (n = 0.02) is triangular in shape with 30° side slopes and a bottom slope of 0.006. Determine the normal depth of flow when the discharge is 4.72 cfs (ft3/sec). Answer:arrow_forwardUniform water flow in a wide brick channel of slope 0.02°moves over a 10-cm bump as in Fig.. A slightdepression in the water surface results. If the minimumwater depth over the bump is 50 cm, compute (a) thevelocity over the bump and (b) the flow rate per meterof width.arrow_forward
- 7. A long triangular open channel with two different side slopes, these are: 2:1 and 3:1 (H: V). The Manning coefficient is 0.014. The longitudinal bed slope =0.004, this channel is converted to the best economic section by using the same amount of material at depth 1.5m in the old section. The old and new flow discharges in m3/s (respectively) are: 9.9 & 57.5 29.8 & 67.3 20.5 & 14.5 19.9 & 37.3 Nonearrow_forwardIn flowing from section (1) to section (2) along a rectangular open channel, the water depth decreases by a factor of three and the Froude number changes from a subcritical value of 0.7 to a supercritical value of 3.4. Determine the channel width at (2) if it is 8 ft. wide at section (1). Assume stead-state flow.arrow_forwardIf a rectangular sharp-crested weir 1.25m long with no end contractions were to replace the triangular weir, what would be the required H in centimeters for a similar discharge?
