36. 3.21. It is proposed to brake a racing car by opening an air scoop to deflect the air as shown in Figure P3.21. You may assume that the density of the air remains approximately constant at the inlet conditions of 14.7 psia and 60-F. Assume that there is no spillage-that all the air enters the inlet in the direction shown and the conditions specified. You may also assume that there is no change in the drag of the car when the air scoop is opened. What inlet area is needed to provide a braking force of 2000 lbf when traveling at 300 mph?

Question
Transcribed Image Text:36. 3.21. It is proposed to brake a racing car by opening an air scoop to deflect the
air as shown in Figure P3.21. You may assume that the density of the air remains
approximately constant at the inlet conditions of 14.7 psia and 60 F. Assume
that there is no spillage that all the air enters the inlet in the direction shown
and the conditions specified. You may also assume that there is no change in the
drag of the car when the air scoop is opened. What inlet area is needed to provide
a braking force of 2000 lbf when traveling at 300 mph?
