I am looking for a tool that can help me simulate the water flow from two water tanks located at different levels. This is in relation with house construction and I would prefer to give priority to water from one tank to be emptied first followed by the other when both are connected to a common pipe.
Please refer me to a free software or an online solution that can simulate my requirement.
The requirement is simple and not really time bound. I am ok to spend time to learn the tool and implement the model for simulation. If it is a clean UI based tool, I believe it should not really take too long provided enough learning resources are available.
