Question

Four objects are being tested to see how they are affected by fluid friction. Object W has a surface area of 4. 5 cm2, Object X has a surface area of 2. 5 cm2, Object Y has a surface area of 6. 2 cm2, and Object Z has a surface area of 3 cm2. Which object would experience the most fluid friction? W X Y Z.

Answer 1

Answer: the most affected object by friction is the Y

Step-by-step explanation:

The fluid friction consists of 2 parts.

viscous resistance and friction with air.

assuming that the objects are in contact with the air, the situation is described by the following equation.

with: C= numerical drag coefficient

p= density

A= Area of the object

v= velocity

so assuming the other variables are constants the area of the object is directly proportional to the fluid friction
