(i) Describe and explain the effect of increased nitrate concentration on algal growth. (ii) Algae do not live long. Explain why the presence of large numbers of algae results in a fall in the amount of oxygen dissolved in the water. (iii) There are very few submerged water plants at Site B. Use (iii) the graphs to suggest how placing a speed limit on boats might allow submerged water plants to become re-established at Site B. ....

Consider an algal cell in the tubular section of the photobioreactor. Assume the algal cell is a perfect sphere of 3 μm diameter and is travelling at 100 cm/s in the tubular region in the same direction of fluid flow. Culture media, which has similar physical properties to that of water (at 25 °C), is pumped through the bioreactor at 200 cm/s. Determine whether flow separation would happen downstream of the algal cell? Justify your answer.
