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 38 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 1.65 in and each refueling took 2.37 min to perform. Calculate the velocity v of the fuel through the nozzle. Assume that the fuel filled the entire cross-sectional area of the nozzle. velocity: m/s
