How much does oil not like flowing under pressure through a 90* unradiused (just like the letter L )?

Just curious.

 

A non radiused fitting is very bad for flow usually.

 

I have a video somewhere of particle flow in a 90 degree bend vs a fully radius bend. Its an eye opener.

 

There is a 90 degree turn in the B oil pumps.

Nobody ever said it wouldn't work............

 

I don't think oil flow velocity is more than 10mph so it's not a huge issue.

 

assuming same velocity, and a minor loss coefficient of 0.2 for a radius 90 degree bend, and 0.3 for a "regular" 90 degree bend, there will be 1.5 times more pressure loss with the non-radiused one.

those coefficients were found online(no picture), as i dont have my book with me, so id have to double check again. but thats the idea about how theyre related.

edit: but then again i just found that the non-radiused one would have a MLC of 1.0, so that would mean that its about 5 times the pressure loss.
