Explain how a top view is developed.
What will be an ideal response?
To draw a top view, the draftsperson goes through a process similar to that required to obtain the front view. However, instead of looking squarely at the front of the object, the view is seen from a point directly above it. When the horizontal plane on which the top view is projected is rotated so that it is in a vertical plane, the front and top views are in their proper relationship. In other words, the top view is always placed immediately above and in line with the front view.

The US EPA’s Maximum Contaminant Level (MCL) in drinking water is 0.005 mg/L or 5 ppb for carbon tetrachloride. The carbon tetrachloride concentration in the soil outside of a factory is 0.01 mg/kg, and the soil has a 1% organic content. carbon tetrachloride has a reported octanol-water coefficient equal to 400. Estimate the organic carbon normalized partition coefficient, Koc, using the estimation procedures based upon equations 2.73 and 2.74 and the sediment/water partition coefficient. Use the sediment/water partition coefficient to predict the possible equilibrium concentration of carbon tetrachloride in the groundwater.
