Hello, I was doing my physics coursework, and blew a hairdryer at my makeshift aerofoil across distances of about 10cm and wind velocities of 8-11 m/s, then measured the lift off of a balance. I found they were proportional, exactly (!?), after doing some research I found drag is proportional to velocity for a laminar flow with no turbulence, could this be a similar case but for just very low wind velocities and lift? The gradient of the trendline on excel was *exactly 1 and no constant on the end (through the origin) for speed vs lift, and so was the gradient of a log graph. The reason is I doubt I will be able to find lift coefficients using the V^2 rule, thank you very much in advance?
