Hydraulic System T-Joint

I am currently a university student working on a simple hydraulic system. When building the system and connecting lines, it is necessary to insert hoses to account for the proper losses in the system. I am trying to insert an oil flushing system that is an intermediate component throughout the system connected by a Tee-joint. I am curious if these Tee-joints are already accounted for just by connecting the line, or if there is a specific joint component in the palette that I am able to use. Through searches it does not seem like there is a specific component. The same goes for flange connections (joints leading into motor/ pump etc.) 

Thanks!

    Hi Jonathan,

    Pipes and hoses represent only inductance, capacitance, and friction within the line. Additional losses like diameter steps or flanges are not considered in these models. Unfortunately, there is no model of tee-joint available. Connections of multiple lines do not have angle and flow dependent losses. As a solution, you could add individual resistors (e. g. LocalResistor) to model a tee. But you have to calculate the resistance yourself (e. g. using Idelchik's handbook of hydraulic resistance).

    The same is true for flange connections, you have to add them as separate resistors. In my experience, however, these losses can very often be neglected, if it is a high-pressure hydraulic system.
