An input stream contains oil sands, comprising 14.0% oil, the remainder being solid sand particles. In the initial stages of steady-state processing, the oil sands are mixed with warm water and pumped to a settling tank. In this tank three layers are formed. The three layers are: 1. Bottom layer containing 95.0% sand and 5.00% water 2. Middle layer containing 5.00% oil and 95.0% water 3. Top layer containing 70.0% oil and 30.0% water The top layer is skimmed off and sent for further processing, while the bottom two layers are disposed of. How much warm water is added to 200 tonnes of oil sands in this process if 85.0% of the total oil is recovered in the top layer (3 sig. figs)? All percentages given are weight percentages.

Question
An input stream contains oil sands, comprising 14.0% oil, the remainder being solid sand particles. In the
initial stages of steady-state processing, the oil sands are mixed with warm water and pumped to a
settling tank. In this tank three layers are formed. The three layers are:
1. Bottom layer containing 95.0% sand and 5.00% water
2. Middle layer containing 5.00% oil and 95.0% water
3. Top layer containing 70.0% oil and 30.0% water
The top layer is skimmed off and sent for further processing, while the bottom two layers are disposed
of.
How much warm water is added to 200 tonnes of oil sands in this process if 85.0% of the total oil is
recovered in the top layer (3 sig. figs)? All percentages given are weight percentages.
