1. (10 points) A field sample of an aquifer is packed in a test cylinder. The cylinder has a length of 120 cm and a diameter of 12 cm. The field sample with a porosity of 0.24 is tested under a constant head difference of 160 cm with water at 10°C. If the estimated hydraulic conductivity of the sample is 30 m/day, calculate (A) the hydraulic gradient along the cylinder: h: 160cm 스.em, yA ,333 mm ? r. (B) the total volumetric discharge (flow rate): KIA 교 -프(D. IQ 4.5 dau (C) the specific discharge: D45 349,65 m a , с 1131-3991 (D) the average linear flow velocity: (E) Could this apparatus be used to test another field sample having a hydraulic conductivity of 86.4 m/day and a median grain diameter of 5 mm? Use the Reynolds number of I as the criterion for the Darcy's law to be applicable.

Using complete sentences, outline two specific examples of how technology advances make the world seem smaller. explain what it means to say the world is “shrinking”

If you could drill a hole straight to the center of the earth, and keep track of what the hole is going through, youwould find: a) you would go through one sort of material, and then a different, denser material, and then a still-different, still-denser material, because the planet is made of concentric layers, sort of like an onion. b) you would go through one sort of material all the way to the center, because the planet is all mixed up. c) if your hole started at the north pole, you would go through different layers of different materials, but ifyour hole started at the equator, you would go through one sort of material all the way to the center. d) if your hole started at the equator, you would go through different layers of different materials, but if yourhole started at the north pole, you would go through one sort of material all the way to the center. e) you would strike diet pepsi when you got to the center.
