The flowrate (q) per unit lenght (ft^2/s) over the spillway shown below is a fuction of the upstream heah H, the acceleration due to gravity g, and the spillway height P. Using dimensional analysis the following pi term was derived: pi= q/g^1/2*P^3/2 If the length scale (lamda) for modeling this spillway is 1:100, and the model q is 0.12 ft^2/s, what should be the design q used in the full scale system?
A 4000-m 3 /day conventional activated sludge plant has an influent with a BOD5 of 190 mg/L and SS of 225 mg/L. What population would this plant serve?
Maintenance expenses for a bridge in west Tennessee are estimated to be $200,000 for the first eight years followed by two separate million dollar expenditures in years 12 and 18. The expected life of the bridge is thirty years.
Assume you are responsible for determining the maximum load that can be carried by a rectangular barge that is 8 m wide and 18 m long. The water line when the barge is empty is 3 m below the level of the cargo deck.
The plate is submerged in a liquid is a vertical position with the parallel sides horizontal and the shorter parallel side at the top and exactly in the surface of the liquid. The static moment of the plate with respect to the surface of the liqui..

water flows through a pipe of diameter 3 inches. If it is desired to use another pipe for the same flow rate such that the velocity head in the second pipe is four times the velocity of the first pipe.determine diameter of pipe
Member ABC is supported by cable CD and a square collar at A that fits loosely over the smooth square rod. Determine the tension in cable CD. The smooth rod is fixed at its base and cannot rotate.
How do you calculate the force of water hitting a concrete cylindrical pole. The velocity of the water is 2 ft/s, the depth of the water is 10 ft, and diameter of the pole is 3 ft. So what would be the total force exerted on the pole by the water?
is fabricated of two 300 mm X 25 mm flange plates and a 800 mm X 16 mm web plate. the plates are joined by four fillet welds that run continuously for the length of the girder. each weld has an allowable load in shear of 920 kN/m.
Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water.
Two ropes are attached to the eye bracket. The resultant force R of the two forces equals 1000-lb and the line of action is directed along the x-axis. if the magnitude of force F1 is 250-lb, determine the magnitude of force F2 and the angle
Three-ply asphalt felt and gravel roof over 2in of insulation board is supported by 18in deep precast reinforced concrete beams with 3ft wide flanges. If insulation weights 3lb/ft 2 and the asphalt roofing weights 5.5lb/ft2, determine the total dea..
