A Boeing 767 due to fly from Montreal to Edmontonrequired refueling. Because the fuel gauge on the aircraft was not working, a mechanic used a dipstick todetermine that 7682 L of fuel were left on the plane.The plane required 22,300 kg of fuel to make the trip. Inorder to determine the volume of fuel required, thepilot asked for the conversion factor needed to converta volume of fuel to a mass of fuel. The mechanic gavethe factor as 1.77. Assuming that this factor was in metric units the pilot calculated the volume to beadded as 4916 L. This volume of fuel was added andthe 767 subsequently ran out the fuel, but landed safelyby gliding into Gimli Airport near Winnipeg. The errorarose because the factor 1.77 was in units of pounds perliter. What volume of fuel should have been added?
