In 1923, the United States Army (there was no United States Air
Force at that time) set a record for in-flight refueling of
airplanes. Using two refueling planes, an Airco DH-4B biplane was
able to remain in flight for 37 h. During the flight, the
refueling planes were able to air-transfer a total of 687 gallons
of fuel to the plane in 9
refueling transfers. Assume that the refueling nozzle had a
diameter of 1.45 in and each refueling took 2.51 min to
perform. Calculate the velocity of the fuel through the nozzle.
Assume that the fuel filled the entire cross-sectional area of
the nozzle.
velocity: m/s
