<s>[INST] # Attempting to analyze the flow of air in a room, the engineer uses a COMSOL model to simulate the airflow through a window. The engineer assumes a uniform cylindrical inflow at the bottom of the window with a flow rate of $1m^3/s$. The air is assumed to be incompressible and the flow is assumed to be laminar and fully developed. For a window of length $1m$, the simulation shows that the flow is restricted to a thin boundary layer near the floor with a thickness of $0.2m$.

Is the solution to the engineer's problem reasonable?[/INST]
