SCFM vs. CFM, also air flow/pressure across a regulator

Of course, unlike
electric current flowing thru a resistor, the oil also
carries heat away. Another chink in the electrical analogy.
Every analogy has limits. The point of this one was simply that losses
occur and result in waste heat, and the current (volume) and voltage
(pressure) behave accordingly. And you can buy junky ones at Radio Shack
(Harbor Freight).
