1.A sample of coarse sand is tested in a constant head permeameter.The sample is 20 cm high and has a diameter of 8 cm. Water flows through the soil under a constant head of 1 m for 15 minutes. The mass of discharged water was found to be equal to 1.2 kg. Determine the hydraulic conductivity for this soil sample. What would be the value of D10 for this sand? Consider C = 1.2.
2.A horizontal channel 4 m wide carries a discharge of 16 m3/s. Determine whether a jump may occur at an initial depth of 0.5 m or not. If a hydraulic jump occurs, determine the sequent depth (conjugate depth) to this initial depth. Also determine the energy loss in the hydraulic jump.
A roadway has a 4% grade intersecting a -7% grade at at station 18+50.00. The grades are connected by an 800 foot vertical curve. A sign is proposed to be installed at Station 15+00.00
engineering ethics course where we have to select a case related to civil engineering with reference to it and discuss
If the landfill is to be constructed to a depth 4 cells, how much area will be required for the landfill if it is to serve the solid waste disposal needs for Tippecanoe County for the next 30 years
velocity of water in the nozzle is given by V=2t/(1-.5x/L)^2. L = 4ft. When x=.5L and t=3s what is the local acceleration along the centerline. What is the convective acceleration.
Find the uniform annual amount that is equivalent to a uniform gradient series in which the first year’s payment is $500, the second year’s payment is $600, the third year’s payment is $7000, and so on, and there is a total of 20 payments.
A 40 mm diameter solid brass shaft in a marine vessel is subjected to a simultaneous torsion of T=250 N.m and axial thrust of P=25kN. Show the combined state of stress on the surface element of the shaft.
Such that E(total) has units of Joules. Assume that kinetic energy = 1/2mv^2, potential energy = mgh, thermal energy = number, magical energy = ObamaCoef*volume*pressure.
estimate the theoretical production of landfill gas (CH4 only) from the degradation of 20.3 kg of rapidly decomposable MSW. asssume the density of methane is 0.7177 kg/m^3.
The Pomdeterra wastewater treatment plant produces thickened sludge that has a suspended solids concentration of 3.8 percent. They are investigating a filter press that will yield a solids concentration of 24 percent.
A laboratory consolidation test was performed on a clayey soil specimen, which was drained on both top and bottom. The time for 50% consolidation was 6.2 minutes, and the specimen's thickness at 50% consolidation was 0.740 in.
The end caps are spherical. The cylinder has length of 30 inc., a diameter of 8 in., and a wall thickness of 0.125 in. Determine the stress in the wall at two points A and B. For each, draw the stresses on a 3-D element. Treat the upper cap as spheri..
A venturi meter is used to measure flow velocity. Given the manometer reading at A is 100 kPa, D = 10 cm, d = 5 cm, VA = 2 m/s, and specific weight of water is 9800 N/m3.
