How Can the Diffusion Equation Help Maximize Water Absorption in Plants?

AI Thread Summary
The discussion centers on finding an equation to compare water absorption by potted plants against evaporation from a water collector. Participants emphasize the need for specificity regarding plant types, as different plants have varying absorption rates. A suggested experimental approach involves measuring water loss in a controlled environment, both with and without a plant, to estimate absorption and evaporation. The diffusion equation is mentioned as a potential tool, but clarity on its application in this context is requested. Overall, the conversation highlights the complexity of quantifying water dynamics in potted plants.

Anyone know an equation for comparing water absorption by plotted plants vs. evaporation of the water collecting in the pot's water collector? That is, if I water a plant and much of the water leaks through to the collection area how much of that leaked water will evaporate vs. be absorbed by the plant?

Your question is too vague. Different plants absorb different ammounts of water. be more spécific

That is extremely vague, but you could start with the diffusion equation

I don't know an equation.You can try this:
Keep the environmental conditions constant through out the experiment.
Leave the pot with 1l of water without putting the plant.
After 1hrs measure the volume of water now.
Put the plant and repeat the experiment.
Now,water lost is = water evaporated+water absorbed.
We know the water evaporated so we can find the water absorbed

This experiment may be inaccurate because plant will reduce the surface area water and light reaching.But this experiment can give a rough result
 
adjacent, that's a helpful suggestion and I might try that, but I was hoping people might know of an equation already.

gabriel, a good equation would simply have a variable for different plant absorption rates, etc.

The_Engineer, could you explain how the diffusion equation would work in this scenario? Thanks!
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
