[QUOTE="Labman, post: 1345022, member: 10678"] Yes. To do a flow calculation, you have to solve an equation for each section. There are some rules of thumb such as a valve or elbow is equal to the length of so many diameters. For laminar flow, back pressure or flow varies as the fourth power of the diameter. A short section of half inch has much higher pressure drop than a longer section of 3/4. [/QUOTE]
