A generator on a research aircraft requires 0.2 slugs per second of cooling air. A cooling air scoop for the generator is designed to be operated while the aircraft is cruising at 200 mph at 20,000 ft above sea level in standard atmospheric conditions. The scoop connects to an opening on the generator casing that has an area of 2 ft2 . Determine the required area of the inlet of the scoop. Also determine the air velocities and pressures at the scoop inlet and at the connection with the generator casing.

Question
A generator on a research aircraft requires 0.2 slugs per second of cooling
air. A cooling air scoop for the generator is designed to be operated while the
aircraft is cruising at 200 mph at 20,000 ft above sea level in standard atmospheric
conditions. The scoop connects to an opening on the generator casing that has an
area of 2 ft2
. Determine the required area of the inlet of the scoop. Also determine
the air velocities and pressures at the scoop inlet and at the connection with the
generator casing.
