Paper Details

Air at 20°C flows at 1 m/s between two parallel flat plates spaced 5 cm apart. Estimate the distance from the entrance where the hydrodynamic boundary layers meet.
GIVEN
Air flows between two parallel flat plates
Air speed (U?) = 1m/s
Distance between the plates (D) = 5 cm = 0.05 m
Air temperature = 20°C
