How to measure the pressure drop across pipes and bends?

Hi, i am currently trying to model a simple structure regarding measurements of the pressure drops across a simple fluid circuit. It consists of pipes and 4 particular 90 degrees bends. However when i tried to combine them together, the measurement read 0. Upon investigating, i realised that the pressure drop across the pipe cancels off the pressure drop across the 4 bends. In reality, it actually adds up instead. May i know how do i model it accurately in Simscape? Please refer to below for a simple schematic diagram.

The pressure loss due to curvature in the pipe bend is given in this link:
If you observe any discrepancy and suspect a bug, please write to the Mathworks Staff.

Is it possible to share this simple model so we can reproduce the problem and look into it? What you described does sound very strange.
