A design for a hovercraft is made. A fan sends air in from the top of the rectangular chamber (60F) and is exhausted between skirts and the ground. Pressure in the chamber is responsible for lift, and the craft is 15 by 7 ft. Weight is 2000lbf. Pressure is stagnation pressure (zero velocity) in the chamber and atmospheric at the exit.Air is incompressible and flow is steady and viscous effects are negligible. WHAT IS THE AIRFLOW RATE NEEDED TO MAINTAIN THE SKIRTS AT A HEIGHT OF 3INCHES ABOVE THE GROUND?
