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)
“Young children...are often uninterested in conversation It is not that they don’t have ideas and feelings, or need to express them to others It is simply that as one eight-year-old boy once told me, “Talking is okay, but I don’t like to do it all the time the way grown-ups do; I guess you have to develop the habit.””
—Robert Coles (20th century)
