Unformatted text preview: agitation cycle, then we have one inflow, no outflows, and accumulation of mass in the system, so it is most probably a transient system. ME 201 Thermodynamics Spring 2006 2 4. Catalytic Converter in an automobile: We consider that we have engine exhaust flowing into the catalytic converter at the same rate that it flows out, so it is most probably a control volume system. 5. Oven: During the cooking the door is closed and no mass enters or leaves the oven, so it is most probably a closed system. 6. Fire inside a room: If we consider a raging fire in a room that already has blown out windows, then we can imagine that we have mass inflows and mass outflows, and mass accumulation or depletion, so it is most probably a transient system. 7. Jet Aircraft Engine: In steady operation we have air and fuel enter the engine and combustion gases leave at the flow rates, so it is most probably a control volume system....
