So a couple of examples, that 90 degree elbow has a K factor of 0.2.

Or that tee fitting that you saw earlier in a video.

Has a K factor of about 0.9.

So let's take a look at some fittings on a excavator.

And so if you, you know, really wanted to analyze what's going on

in the flow of the fluid of these excavators so starting here is a

smooth, gently changing diameter conduits, so you can probably take this as a laminar

flow and calculate the pressure drop across its conduit based on its length.

Then over here, once we get up to these

pipes when you're going way up over here and, getting

to the cylinder, you've got a, two 45 degree

bends here, so you want to take into account fitting losses.

You get into the cylinders, this is the 90

degree bends, so you want to calculate the losses there.
