I have a pipe with two inlets and one outlet. Its basically a Y shaped pipe. I am trying to run a pressure drop analysis of it but I do not have any outlet data. All I have is that both inlets are exposed to a mass flow of 0.2kg/s and both are exposed at the inlet to atmospheric pressure. Solidworks flow doesnt allow you to put more than one boundary condition per surface so how would I go about finding the outlet pressure and pressure drop (outlet mass flow is also unknown)

Hi Eddy,

The mass flow rate into the system must be the same as the mass flow out of the system. So in a steady state system, if each inlet is 0.2 kg/s then conservation of mass would mean that the outlet mass flow will be 0.4 kg/s.

Therefore if we apply a static pressure on the inlet, and an outlet mass flow of 0.4 kg/s then you should have enough to run the simulation.

Hope this helps

Cheers

Steve
