What wing area should a plane weighing 2000lbs have to enable it to land at a speed of 35mph? Max CL= 1.50 Formula for lift lb= CL*ρ*A*v^2/2 when i set up the problem i get this 2000= 1.50*ρ*A*(35)^2/2 and i realize I am trying to solve for A (area) but what does the ρ...

The problem: A canal cut in rock (n= 0.030) is a trapezoidal in section with a bottom width of 6.10m and the side slopes of 1 on 1. The allowable average velocity is 0.76 m/s. What slope will produce 5.66 m^3/s? The books answer is 0.000675 from the mannings equation V=(1.486/n)R^2/3 x...
