In a static test, a turbofan engine with a bypass ratio of 9 has a core hot exhaust speed 1.5 times that of fan exhaust speed. The engine is operated at a fuel to air ratio of f = 0.03. Both the fan and the core streams have no pressure thrust. The ratio of fan thrust to thrust from the core engine is _______. (round off to one decimal place)
Correct : 5.7 to 6.0
