In sailboating, the wetted area is the area of the hull which is immersed in water.
In aircraft, the wetted area is the area which is in contact with the external airflow. This has a direct relationship on the overall drag of the aircraft.
Famous quotes containing the word area:
“The area [of toilet training] is one where a child really does possess the power to defy. Strong pressure leads to a powerful struggle. The issue then is not toilet training but who holds the reins—mother or child? And the child has most of the ammunition!”
—Dorothy Corkville Briggs (20th century)
