# Simulation Quiz 4

### Simulation of an Exhaust Manifold

An Exhaust Manifold consists of multiple inlets and a single outlet. Inlet Ports are fitted snugly with the Exhaust Valve, with no clearance, but with relative sliding between the two parts. Outlet Port is fitted snugly with the Catalytic Converter, with no clearance. The exhaust gases passing through the Manifold exert an exhaust back pressure of 0.05 MPa against the inner faces of the wall. Analyze this model using the Submodeling approach for the region of interest.
