Hey everyone! My name is Jing and I am participating in a one month summer program called SHAD where 800 high school students across Canada come together to try and solve some of the world's most multi-dimensional problems. One of the aspects of this program is the Entrepreneurial Project, where groups of SHAD participants innovate a solution to these kind of problems. This year's theme is every consumption, and one of our group's ideas is to create a new type of pipes which has swirled grooves on the interior to better permit water flow and limit turbulence. A picture of the interior of a rifle is shown below to help illustrate what I am trying to convey: My question is whether or not this is a feasible idea and if it can be effective in reducing energy losses in the water across long distances. Thanks for any help in advance!
