Thank you for your answer! So basically, if i calculate all the losses (for V1, V2, V3) and then apply them on the formula so that V0=L1V1+L2V2+L3V3 i should have the proportional volumetric flows? I guess the first step is now to calculate all the separate loss for the different sections.

Hi! Yes, i have the circumference and lengths of all sections. All the sections have the same circumference. I did not include specific values in the description since i do not want people to solve it completely, but rather help me get started . What i thought of was using bernoulli's equation, but the question is how? I have never done calculations for a system that splits before. Trying to create an m-file in matlab for this allso. Will be working with it all day if i have to!

Hi! If i have an airduct with a fan in it creating a volumetric flow V0 with the following construction: V0 | |----- V1 | |-----V2 | V3 Where the airduct branches into 3 sections. The friction of the airduct is known and the loss coefficient is 0. Also, the pressure before the fan is 1bar and so is the pressure after V1,V2, and V3. The diameters and lengths of the duct sections are known and the density of the air is 1.2. How can i calculate V1, V2 and V3? PS sorry for the crappy english =)
