A square building (15 m × 15 m in plan) is to be constructed on a site where the soil profile consists of 3m of clay with an over-consolidation ratio that varies from 5 at the surface to 2 at 3m overlying a 5m thick clay layer with an over-consolidation ratio of 2, which overlies rock. The soil properties are Cc = 0.4, Cr = 0.1 and ?sat = 18 kN/m3 for both clays, and the water table is 1 m below the soil surface. Determine the settlements when a stress of 60 kPa is applied by the building. To determine the initial void ratio assume Gs = 2.65. Assume also that settlements of any sand and gravel layers can be ignored.
A waste water sample contains 2.092mmol/L NaCl. Calculate the concentration of NaCl in mg/L. What are the mmol/L concentrations of Na and Cl. Na = 23 and Cl = 35.5.
Air flows steadily between two sections in a long, straight portion of 4 in. inside diameter pipe (D1=D2). The uniformly distributed temperature and pressure at each section are p1=100psia, p2=18.4psia, T1=540 R and T2=453 R.
Given that uniform flow is subcrital and there is a weir in a rectangular channel, how do you determine what the weir height should be to force the flow to be critical. Draw this transition on a specific energy curve.
a moisture content of 10.2 % and a specific gravity of solids of 2.65. Compute the unit weight, dry unit weight, degree of saturation, void ratio and porosity.
A wave has a height of 1.5 m in water 5 m deep and a wave period of 6 s. Plot the horizontal component of velocity, the vertical component of acceleration, and the dynamic pressure at a point 2 m below the still water level versus time for a 6-s i..
A rectangular plate 5ft by 4ft is at an angle of 30 degrees with the horizontal, and the 5-ft side is horizontal. Find the magnitude of the force on one side of the plate and the depth of its center of pressure when the top edge is (a) at the wate..
how to find degree of kinematic indeterminacy
A nozzle is designed to linearly accelerate the fluid from V1 to V2 (i.e., V = ax +b, where a and b are constants). Determine the local acceleration, the convective acceleration, and the total acceleration at point 1 and 2 at t = 0.
Roe is the ratio of nonprestressed reinforcement in a section, and roe balanced is the ratio of tensile reinforcing producing balanced strain condition. Show cross sections, including bar sizes, arrangements, and spacing.
The 24-in pipe leads from a reservoir (flush entrance), and the 18-in pipe discharges into the air at a point 15 ft lower than the reservoir water surface level. Assuming all changes in section to be abrupt
one atmospheric air stream at 15 c and 30 percent relative humidity is mixednadiabatically with another air stream at 30c and 70 percent relative humidity in a steady flow process
A light bar AD is suspended from cableS and supports a 20 kg block at C. The extremities A and D of the bar are in contact with frictionless, vertical walls. Determine the tension in cable BE and the reactions A and D
