Thank you for all the input ... the pipe is copper the id is .5 its actually two 24" lengths joined by two 90s and a 4" section of pipe to make a long U the flow is 2.5 gpm.
Once again thank you for all the help.
I am looking for a simple formula to compute pressure drop in a straight new pipe(basically no friction). Its just a simple 2' straight pipe with water flowing in it. How do you figure pressure drop? Is there a simple formula for pressure drop in a pipe?
Thank you for your time.
