For our investigatory project, I and my groupmates are going to test the efficiency of water cress in cleaning wastewater. We're going to adapt the concept of the Green Roof Water Recycling system, where the wastewater from kitchen and bathroom sinks gets pumped up to the roof and gets trickled onto some semi-aquatic plants. Gravity brings the water back down for reuse. Anyway, I thought I might figure out how long I should put the water cress in the wastewater using the acceleration of gravity (9.8 m/s2) and the length/distance of the original GROW set-up, which is 4m. The question is, what's the equation going to be? Something similar to, um, the time equation involving speed (t = d/s)?
I really hope someone can answer these questions for me... thank you! ^___^
