1.An aquifer has the following properties: K=0.0001 cm/s, hydraulic gradient=0.12, cross-sectional area=10,000 ft^2, porosity=0.30 Calculate a) k(intrinsic) (m^2) b)k(intrinsic) (darcy) c)specific discharge (m/s) d)discharge (gpm) e)avg linear velocity (m/d)
2.When you allow a can of carbonated beverage to sit open so that the carbon dioxide is released to the air, does the pH of beverage remain the same, increase, or decrease? Explain.
3.A simple beam of Douglas-Fir Larch, select grade, has a span of 18 ft with two concentrated loads of 3 kips each placed at the third points of the span. Neglecting its own weight, determine the size of the beam with the least cross-sectiona; area based on bending stress.
