which is better... when sending a copper pipe 90 degrees... is is better to make it 90 or use 2 times 45 degrees... all this of course for the sake of flow!

thanks!

You did not state if this is drainage or heating or water supply.

In any event the best way to avoid excessive friction loss without a doubt is the use of 45 degree fittings

The equivalent pressure loss for example from what I remember in 2" nominal copper the standard ell would be 5.5 feet of tubing and a 45 degree would equal 2

On 3/4 an 90 = 2 and a 45 =.5

Try to use wrought copper fittings as opposed to cast as the internal area is smoother
