A contractor wants to build a fill at his new construction site. He has two options for purchasing his borrow material. Site A has a soil with a unit weight of 2.5 kN/m3, a moisture content of 14% and a cost of $8 per cubic meter. Site B has a soil with a unit weight of 17.9 kN/m3, a moisture content of 25% and a cost of $6 per cubic meter. If the contractor needs a fill with a volume of 100,000 cubic meters and will place the material with a dry unit weight of 18.7 kN/m3, how much borrow material will he need to purchase? Which soil is the cheaper purchase for the site?
Determine the magnitude of P if 10sec is required for the package to travel 5 m up the incline. The static and kinetic coefficients of friction between the package and the incline are both equal to 0.3
The new owners propose to flush the pond into their discharge pipe leading to the Atlantic Ocean, which has a salt concentration above 30,000 mg/L. What flow rate of fresh water (in m3/s) must they use to reduce the salt concentration
A well of 0.4 m diameter fully penetrates a 25 m thick confined aquifer of coefficient of permeability of 12m/day. The well is located in the center of a circular island of radius 1 km.

The frame is designed to carry the hanging mass at G equal to 167 kg. The frame is supported by a pin connection at C and the rope AB, and constructed with pin connections at points E, F, and D. Importantly, members BEFG and EDC are continuous mem..
A permeameter with a cross-sectional area of 400 cm2 contains 3 soils in 50 cm thick layers. A total head difference of 2.0 metres results in a flow rate of 100 cm3/s. The head loss through the top layer of soil is 50 cm.
