A 2.1 m diameter sewer is laid on a slope of 0.0032 m/m. If the Manning's Coefficient for the sewer is equal to 0.015 at all depths and flows, determine:
a) flow (Q) and velocity (V) when the sewer is flowing full,
b) Q and V when the sewer is flowing at a depth of 0.7 m,
c) Q and V when the flow in the sewer is at 60% of its capacity, and
d) V and depth of flow when Q = 1.6 m3 /s
A fully loaded, ocean going container ship is just stable about its longitudinal axis (roll). The ship has a total weight of 155,000 tons, length = 1,600 feet and a beam = 150 feet (assume that it is the shape of a rectangular box). Calculate the ..
If 90% of the weight of this brown sugar is sucrose (C12H22O11), what mass of dissolved oxygen would have been required to degrade this mass of sucrose had some not been recovered from the barge prior to its dissolution and dispersion into the river?
A 3-ft diameter column with weight of 150 kg is placed on top of 1 m thick aggregate layer. The soil beneath the aggregate layer is sand. The friction angle of the aggregate is 36 degrees and the unit weight is 22 lb/ft3. What is the pressure acti..
The suspended load exerts a force F = 600 lb at A and bar OA weighs 200 lb. Assume that the bar’s weight acts at its midpoint. Determine the tensions in the cables and the reactions at the ball and socket support O. Draw complete FBD(s) for full cred..
A 200lb homogeneous gate of 10ft width and 5ft length is hinged at point A and held in place by 12ft long brace as shown in fig 2.69 as the bottom of the brace is moved to the right the water level remains at the top of the gate. the line of action o..
A Pelton wheel, located at an elevation of 200.0 m, is used to extract power from a reservoir at an elevation of 800 m. A penstock 1500 m long and 0.8 m in diameter connects the reservoir with the nozzle of the Pelton wheel.
A chemical is added at the beginning of a water treatment plant at a dose of 750 lb/day. The water treatment plant provides water to a community of 200,000 people and the average water consumption in the city is 110 gallons per capita per day (gpcd).
Compute points on the velocity profile from the pipe wall to the centerline of a 3/4-in Type K copper tube if the volume flow rate of water at 60 degrees F is .50 gal/min.
Explain the process for establishing a centerline for a roadway for an existing road. Include a description of the types of property markers used as well as any problems a surveyor may encounter in this process
An earth retaining structure is 12 feet high. The soil behind the earth retaining structure is a sand having a moist unit weight equal to 125 pcf, a saturated unit weight equal to 130 pcf, and a friction angle equal to 32 degrees.
A vehicle is traveling on a curved section of a road of radius 2500 feet at a speed of 60 mi/h. The motorist suddenly applies their brakes, causing the automobile to slow down at a constant rate. After 8 seconds the speed has been reduced to 45 mi..
A reservoir has a capacity of 2.75 million acre-ft. How many years would this supply a city of 100,000 people if evaporation is neglected. Assume a use rate of 180 gpcd.
