Message: [QUOTE="andharri, post: 1536558, member: 31258"] You are right that equation is for a steady state system and any real system is dynamic, like the operation of an engine. However, the ways in which pressure, radius, and volumetric flow rate are related are all described from the general Navier-Stokes relation, from which Hagen-Poiseuille can be derived, and nonetheless exhibit similar tendencies in regards to changes in one affecting the other (the strength of the relationship with radius can vary depending on geometry). I think FFD does a great job as well, however this particular product just isn't jiving with what I know about fluid dynamics or how the 7.3l oil system operates. EDIT: "If you increase the radius of the pipe it makes for a larger area. A larger area means more volume. More volume means you need more pump to make up the difference. If you decrease the total volume needed then you need less pump to meet demand." This is not necessarily true because the volume that the pump is making up is the volume that is lost through the hose, or flows through it (the volumetric flow rate). The flow rate is really determined in this system by the injector demand, not the pipe or log that feeds it. Therefore, the system volume doesn't matter as much as the flow rate, which is determined by the injectors and the programming. [/QUOTE]
