The boeing 787 dreamliner is designed to be 20% more fuel efficient than the comparable boeing 767 and flies at an average cruise speed of mach 0.85. the midsize boeing 767 has a range of 12,000 km, a fuel capacity of 90,000 l, and flies at mach 0.80. assume the speed of sound is 700 mph, and calculate the projected volumetric flow rate of fuel for each of the two dreamliner engines in m3/s. (25 pts)
(a) assume that the fuel lines for each engine in the boeing dreamliner are 7/8 inches in diameter and that the density and viscosity of jet fuel are 800 kg/m3 and 8.0 ∗ 10−3 kg/(m · s), respectively. calculate the average velocity of the fuel in m/s and the reynolds number of this flow. state if the flow is laminar or turbulent.
