An anchored sheet pile wall is shown in Figure P15.14. Determine the embedment depth, the maximum bending moment, and the force on the anchor per unit length of wall. Use either FSM (F∅ = 1.25) or the NPPM with (FS)r = 1.5. Assume the soil above the groundwater to be saturated.
A stream with a flow of 22 mgd contains 180 mg/L of sodium cyanide in the form of NaCN. Chlorine can be added to destroy the NaCN waste according to the reaction shown below. Find the theoretical minimum amount of chlorine required (in lb/day).
The pavement is on a base which has a modulus of subgrade reaction of 250 pci. A 17,000 lb corner load is applied (al is 7 inches). Using the revised Westergaard equations, find the modulus of elasticity of the pavement if a corner deflection of 0..
The pollutant has a reaction rate coeeficient k of 0.25/day. Assuming is pollutant is well mixed in the lake, find the steady-state concentration of pollutant in the lake.
The engineering team at Manuels Manufacturing, Inc., is planning to purchase an enterprise resource planning (ERP) system. The software and installation from Vendor A costs $380,000 initially and is expected to increase revenue $125,000 per year ever..
Two waters are in equilibrium with air, one at pH 9.5 and one at pH 7.3. these waters are mixed in 1:1 proportions. Assuming that carbonate species dominate the acid/base behavior of boh solutions and that no gas transfer occurs when they are mixed
This unit enables learners to develop an understanding of the methods and techniques used to create civil engineering structures and the skills needed to solve problems associated with civil engineering activities
When a rocket reaches an altitude of 40 m it begins to travel along the parabolic path (y-40)^2=160x, where the coordinates are measured in meters. If the component of velocity in the vertical direction is constant at Vy=180m/s
A new chemical remediation tank is needed. Current technology tanks, which costs $150,000, MUST BE DRAINED AND TREATED EVERY TWO YEARS AT A COST OF $30,000; THE TANKS WILL LAST TEN YEARS, AND EACH WILL HAVE A SALVAGE VALUE OF 5%. OF FIRST COST.
Discuss the type of hardening rule you would use to model the cyclic constitutive behavior of the composite.
A stream with a flow of 22 mgd contains 180 mg/L of sodium cyanide in the form of NaCN. Chlorine can be added to destroy the NaCN waste according to the reaction shown below. Find the theoretical minimum amount of chlorine required (in lb/day). How w..
