Guys,

	I have to agree with Scott here.  From a standpoint of numerical 
modeling, you can think of pressure as analogous to voltage in the 
electrical domain, and volume, amperage.  They are two very different 
variables, which measure different things.  For example, a 
fuel injector has 40-60psi of pressure with very small flow.  A river 
OTOH, has less than 1psi, but flows _ALOT_.
