Keeping things simple, this is why you see a general % loss factor applied since getting into the fine details is not worth the effort (fluid choice, viscosity, mass of components, etc).
That makes sense, but when you switch to different fluids will you see the power loss decrease at all? I'm not interested in doing any of this but I want to understand it.
