There is something in the following page from the documentation that I would like to know more about:
Normally, the equation for the pressure loss in a pipe (I will use the turbulent case as an example) should look like:
Delta_p = f * ( (m_dot^2) / (2 * rho * D * S^2) ) * Length
(I am putting the Length in the end for convenience)
In the case of Simscape Fluids, according to the formula in the doc:
Length = (L + L_eqv) / 2
So my question is, does L_eqv stand only for the equivalent length of resistances, or the actual length plus the equivalent length?
If it only stands for the length of resistances, it seems that the length used for the calculations is being reduced by roughly a factor of two (with respect to what I have seen in the literature) by doing the mean of both, thus I would be seeing less pressure losses than he expected.
Is this correct?
