Lift coefficient Definition and 10 Threads

I'm confused about how to solve for the Cl. I know that the equation for lift is L = Cl * r * .5 * V^2 * A, and you need the Cl to find lift. However the equation for lift coefficient that I found is (2L)/(1/2*p*u^2*S) and you need L which is lift to solve for Cl. So i don't understand how in...

I was trying to look for an L/D ratio published everywhere on the web and I can't seem to find it for our project. Since I couldn't find it, I wanted to try calculating myself. Can't seem to find $$C_l$$ or $$C_d$$ though without some sort of paywall on research papers. So L/D would just be...

Hi, I am looking into aerodynamic parameters for rockets (ogive nose, cylindrical body of different diameters, four fins at bottom) and have a question about the lift coefficient. If a rocket is launched vertically, with zero incidence angle and wind, would that result in a very small lift...

I need an equation that solves for the height of a projectile at a specific x position. The known variables are spin of the ball, initial position, initial velocity, initial launch angle and the drag and lift coefficients.

Please go to this Wikipedia article on Lift Coefficients, and behold the first formula. The last part of the equation has a "S" which is supposed to stand for "relevant plan area". Now, there was no explanation of what this "relevant plan area" is or means. I was guessing that it means the...

How can I find an equation to calculate the lift coefficient on a basketball at different launch velocities? I looked at different papers explaining the physics of basketball throws but all i could find was an equation for the drag coefficient: -mv +1/2 ρ A Cd v^2 = mv

Been working on a new way of determining the lift coefficient besides the thin airfoil theory,and I don't know if there is already such a method or if I'm wrong.Plz Help.We know, L=CL×1/2ρv^2A Now,as lift is a force,then it should be as L=mμ, where μ is the "upwards acceleration". So...

Consider a proposed airplane design shape in a wind tunnel. The forces and moments are measured at the proposed center of gravity location. At zero angle of attack, pitching moment is zero and lift is 10N. At 5 degrees angle of attack, pitching moment is -5Nm and lift is 60N. The chord of the...

I have some aerodynamics homework to finish up, and I am not really sure how to do one part. Question is: What is the corresponding zero Mach number lift coefficient I can't find an equation in my book or anything. Can someone maybe shed some light? My first two questions were to...
