Coefficient of Drag

Description:

The coefficient of drag is a dimensionless quantity that measures the resistance of an object to movement through a fluid (usually air) and determines the efficiency of its shape in reducing drag.

Senses:

Physics: In physics, the coefficient of drag refers to the ratio of the drag force on an object to the product of the square of the relative velocity between the object and the fluid, the density of the fluid, and the reference area.

Aerodynamics: In aerodynamics, the coefficient of drag indicates the drag performance of an aircraft or vehicle. It is an important parameter to assess the efficiency of design and streamline shape.

Sample Sentences:

1. The coefficient of drag for the new car model was significantly lower, resulting in improved fuel efficiency.

2. The researchers conducted experiments to determine the coefficient of drag on different shapes in order to optimize the design.

3. Changing the surface texture of the golf ball can significantly affect its coefficient of drag, resulting in altered flight characteristics.

4. The engineers performed wind tunnel tests to measure the coefficient of drag for the new airplane prototype.
