SOLVED:A separate-flow turbofan engine is shown at cruise condition. The flight condition, air and fuel flow rates, nozzle exit conditions and fuel properties are all labeled in the schematic drawing (Figure P4.67). The primary and fan nozzles are of convergent type and both are choked, as shown. Calculate (a) ram drag in kN and lbf (b) fan nozzle exit area, A18, in m^2 and ft^2 (c) fan nozzle gross thrust in kN and lbf (d) core nozzle exit area, A8, in m^2 and ft^2 (e) core nozzle gross thrust
