I am looking to bypass an existing sewer pipe with another pipe. The existing pipe is rectangular, approximately 9'x5'. I am looking to use a circular bypass pipe of 6' diameter. Since the velocity of "water" flowing thru the pipe will be the same then I need to compare the surface areas, correct? The surface area of the 6' diameter pipe is 28.3 SF. Normally to find the surface area of the rectangle I would take l*w to get 45 SF BUT since I am comparing flows do I need to use Hydraulic Diameter of the rectangular pipe and then find the surface area using pi*r^2? Doing it that way I get a surface area of 32.2 SF.
Can I do that? Is that because the flows thru a circular pipe has less turbulence? thanks.
