Basic Ideas
There are two basic paradigms:
- Version with pressure induced by gravity. Large tanks of water are held up high, or are filled to differing water levels, and the potential energy of the water head is the pressure source. This is reminiscent of electrical diagrams with an up arrow pointing to +V, grounded pins that otherwise are not shown connecting to anything, and so on.
- Completely enclosed version with pumps providing pressure only; no gravity. This is reminiscent of a circuit diagram with a voltage source shown and the wires actually completing a circuit.
Applications: Flow and pressure variables can be calculated in fluid flow network with the use of the hydraulic ohm analogy. The method can be applied to both steady and transient flow situations.

Famous quotes containing the words basic and/or ideas:
“We can’t nourish our children if we don’t nourish ourselves.... Parents who manage to stay married, sane, and connected to each other share one basic characteristic: The ability to protect even small amounts of time together no matter what else is going on in their lives.”
—Ron Taffel (20th century)
“Most advice on child-rearing is sought in the hope that it will confirm our prior convictions. If the parent had wished to proceed in a certain way but was made insecure by opposing opinions of neighbors, friends, or relatives, then it gives him great comfort to find his ideas seconded by an expert.”
—Bruno Bettelheim (20th century)
