1000 L of oil (Density=0.8) spills into a river flowing at 100 cfs. If it takes the oil an hour to spill into the river, what is the concentration of oil after all the oil has spilled (after one hour)? If in the second hour, 50% of the oil is removed, what is the concentration of oil after two hours?

A massive oil spill in the gulf unleashes approximately 20,311 barrels of oil into the Gulf each hour. This creates an expanding circular layer of oil on the water’s surface about 1/16 inches thick with the center being the source of the spill. Letting R(t) represent the radius (in miles) t hours after 6:00pm, the growing radius of this oil spill can be modeled by the formula: R(t)=1/2 ?(t+1) 1.) What time did this spill start? (When was the radius...

An accidental spill results in a total volume Vo = 100 gallons of a toxic liquid chemical entering the upper portion of an unconfined aquifer. The aquifer has a porosity η = 0.25 and a hydraulic conductivity K = 10-3 m/s. The density of the liquid chemical is € ρℓ = 1200 kg/m3 and sorption to solids is negligible. Groundwater samples show that the chemical quickly dissolved in the groundwater, forming a "blob" with a total volume (soil and porewater)...
