Hello Everyone,
I have a uniform cross section pipe having mass flow rate at inlet. I wants to know what will be the value of pressure just before the outlet and pressure drop along the pipe. I need help to set BCs for that. The inlet boundary condition set as velocity inlet but don't know what to set at outlet. My question may silly but need help. |

You can set the pressure outlet to 0 pa or to a certain pressure depending on the downstream condition of the pipe.
To calculate the pressure drop it will simply be Inlet Pressure - Outlet Pressure. In the case of 0 pa outlet, the pressure drop will be equal to the Inlet Pressure. You can calculate the inlet pressure using the "surface integrals" in the results tab.
