An aquifer has a uniformity coefficient of 3.5 and a d1o - 0.5 mm. At 20°C, estimate the hydraulic conductivity at 20 degrees Celsius using methods that meet their applicable restrictions. Compare your range of results with other hydraulic conductivities that are known (reference your source) for unconsolidated formations and give possible soil classifications.

Part 1 How fast do small water droplets of 0.23 um (23 x 108 m) diameter fall through the air under standard sea-level conditions? Assume the drops do not evaporate. Repeat the problem for standard conditions at 5000-m altitude. (a) For the condition that the droplets are falling at a constant velocity, what is the relation between the weight ofa drop W, the buoyancy force Fe, and the drag force F? (b) What is the expression for the weight of...

graphs
2. Consider an NACA 23015 airfoil (Fig 5.2a and 5.2b in text) with a chord of 0.64 m in an airstream 1000m above sea level conditions. The freestream velocity is 70 m/s. The lift per unit span is 1200 N/m. Calculate the angle of attack and the drag per unit span.
