computational fluid dynamics
 

I'm trying to solve a mixing problem and hope someone can advise me on a good source for information. The well pumps around 950 gpm into a 12" main it proceeds through two 90 degree angles travels appox. 200 feet before it tees into the distribution system. Assuming the flow is one direction it then travals another 450' before it reaches its first customer . How much water would mix with 16 gallons of chemical that has been injected?
