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 ideas, basic and/or ideas:
“Our basic ideas about how to parent are encrusted with deeply felt emotions and many myths. One of the myths of parenting is that it is always fun and games, joy and delight. Everyone who has been a parent will testify that it is also anxiety, strife, frustration, and even hostility. Thus most major parenting- education formats deal with parental emotions and attitudes and, to a greater or lesser extent, advocate that the emotional component is more important than the knowledge.”
—Bettye M. Caldwell (20th century)
“Nothing and no one can destroy the Chinese people. They are relentless survivors. They are the oldest civilized people on earth. Their civilization passes through phases but its basic characteristics remain the same. They yield, they bend to the wind, but they never break.”
—Pearl S. Buck (1892–1973)
“What persuades men and women to mistake each other from time to time for gods or vermin is ideology. One can understand well enough how human beings may struggle and murder for good material reasons—reasons connected, for instance, with their physical survival. It is much harder to grasp how they may come to do so in the name of something as apparently abstract as ideas. Yet ideas are what men and women live by, and will occasionally die for.”
—Terry Eagleton (b. 1943)
