As you know from the behavior of a nozzle, when a fluid like air is accelerated, the pressure drops. This is exploited in racecars. The air is channeled under the vehicle at the front like a nozzle and then returned to ambient pressure at the rear with a diffuser. For a formula one car traveling at 100 mph, that is 2.0m wide and 5.0m long, the pressure drop is sufficient to double the downforce. The car's mass is 800kg, what pressure must the air have beneath the vehicle, and how fast must the air be traveling under the vehicle? Assume 300K, 100kPa for the ambient air temperature and pressure.
