What Is the Required Wing Area for a 2000lb Plane to Land at 35mph?

In summary, the formula for lift is lb= CL*ρ*A*v^2/2 and to calculate the wing area for a plane weighing 2000lbs to land at 35mph, we set up the equation 2000= 1.50*ρ*A*(35)^2/2 and solve for A, where ρ represents the density of air at the landing strip.

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 stand for? I read its stands for the density of the fluid

The rho is density of air at the landing strip. Watch your units!
 

FAQ: What Is the Required Wing Area for a 2000lb Plane to Land at 35mph?

What is drag on an airplane?

Drag is the resistance or force that acts against an airplane's forward motion through the air.

What causes drag on an airplane?

Drag is caused by several factors, including the shape of the airplane's body, the wings, and any additional parts such as flaps or landing gear. The speed and direction of the wind and the air density can also affect drag.

How does drag affect an airplane's flight?

Drag can significantly impact an airplane's flight by slowing it down, reducing its efficiency, and increasing fuel consumption. It can also cause the airplane to lose altitude or make it difficult to maintain stability.

How do airplanes reduce drag?

Airplanes are designed to minimize drag through aerodynamic principles, such as using streamlined shapes and smooth surfaces. Other methods include retractable landing gear, winglets, and reducing the number of external protrusions.

Can drag be completely eliminated on an airplane?

No, it is impossible to completely eliminate drag on an airplane. However, engineers continuously strive to reduce it as much as possible to improve the airplane's performance and efficiency.
