Aircraft Performance Question -- Berguet

In summary, the question asks what cruise velocity would maximize the cruise range for an aircraft with a mass of 14000kg (excluding fuel), 2500kg of fuel, a specific fuel consumption of 2.8x10^-5 kg/N/s, a drag polar equation of CD = 0.02+0.08CL^2, and a planform area of 65m^2. The Breguet equation and coefficient of lift are relevant for solving this problem, but the given information does not include a specific velocity or coefficient of lift, making it difficult to find a solution. The poster is currently stuck in a loop, trying to find one without the other. They may need to consider the details and reasoning

Homework Statement


What cruise velocity should the aircraft fly to maximize the cruise range?
Aircraft mass (excluding fuel), m0= 14000kg
Mass of fuel, mf = 2500kg
Specific fuel consumption of aircraft engine, sfc = 2.8[itex]\times[/itex]10-5 kg/N/s
Drag polar, CD = 0.02+0.08CL^2
Planform area of aircraft wings, S = 65m2

Homework Equations


Breguet Equation
Coefficient of Lift

The Attempt at a Solution


I am trying to find the coefficient of lift but there has been no given velocity. I then try to find the velocity but there is no given coefficient of lift. I feel like I'm going around in circles.
Cl=2L/ρV2S
L=W (14000+2500)[itex]\times[/itex]9.81=161865N

Are you not assuming uniform level flight?
Does that not make the lift equation rather simple?

How about showing the details of the working, with reasoning, that you have already.
