Three piezometers located 1000 m apart bottom in the same horizontal, confined aquifer. Hydraulic conductivity is homogeneous. Piezometer A is due south of piezometer B, and piezometer C is to the east of the line AB (and 1000 m from both A and B). The surface elevations of A, B, and C are 95 m, 110 m, and 135 m respectively. The depth of water in A is 10 m, in B is 40 m, and in C is 35 m.
A. Make a map of the piezometric surface, drawing equipotential lines at increments of 5 m.
B. What is the hydraulic gradient in the aquifer?
C. If the hydraulic conductivity of the aquifer is 2 x 10^-4 m/s, what is the volumetric flux?
D. If the aquifer is 35 m thick, how much water flows across a line 1 km wide (where the line is perpendicular to the direction of groudwater flow)?

Design a riveted end plated Connection between a beam ISHB-300 and the flange of the Column ISHB-200 to transfer a vertical factored shear of 125 kN and a factored hogging bending moment of 125kNm.Use Shop rivets of 20mm dia.
Draw the influence line for the shear at point B. Plot numerical values every 5 ft. Assume the support at A is a roller and C is fixed. EI is constant.
Each month the speedy dry Cleaning company buys 1 barrel (0.160 m^3)of dry cleaning fluid . Ninety percent of the fluid is lost to the atmosphere and 10 percent remains as residue to be disposed of.
Determine appropriate dimensions of the finished water clearwells to achieve adequate disinfection using chlorine. Flow Rate Q = 30 million gallons paer day.
A town is going to upgrade its primary WWTP to a secondary plant that can meet the effluent standard of 25 mg/L BOD5 and 30 mg/L suspended solids. They have selected a CSTR activated sludge system for the upgrade.
The probability is 1% that an electrical connector that is kept dry fails during the warranty period of a portable computer. If the connector is ever wet, the probability of a failure during the warranty period is 5%.
Estimate the constant rate of withdrawal (in m^3/s) from a 1375 ha reservoir in a month of 30 days during which the reservoir level dropped by 0.75 m in spite of an average inflow into the reservoir of 0.5 Mm^3/day.
A 2.0m-wide strip at a depth of 1 m in a stiff clay carries a wall load of 425 kN/m. The saturated unit weight of the caly is 20kN/m^3. TRiaixal tests give the following results: c'=10 kPa, phi'=28 degree, cu=105kPa, and phi_u = 0.
