In our example, the flow will be the water from the faucet and the valve will be the faucet. In our first example, the converter will represent the temperature of the water. This simply connects the different converters to other components. They are sometimes called connectors. In our first example, the connector will connect the temperature converter to the valve.
Natural system s are complex and hence require complex models to explain their behavior.
One common framework for studies of natural systems is the in-out model in which we view a system or a system component by the flow of energy or matter in and out of it. To illustrate this, we begin with a simple bathtub model, as it is such a clear example of a reservoir, flow, and valve system which you've had plenty of experience with. Let's consider the diagram and its concepts. A model is an excellent way to represent a system in its most essential form. Such sketches should always be representative, very basic with essential elements we think we need to work with.
