# Some ceiling fans have decorative wicker reeds on their blades. Discuss whether these fans are as quiet and efficient as those with smooth blades.

The ceiling fan with decorative wicker reeds on its blades is less efficient than the ceiling fans with smooth blades.

See the step by step solution

## Step 1: Speed

The rate at which the location of an object changes in any direction. The ratio of distance traveled to the time it took to travel that distance is known as speed.

## Step 2: Explanation

The decorative wicker on the blades affects the rotation of the motor and reduces the speed of the motor. As a result, the ceiling fans with decorative wicker reed on their blade become less efficient.

## Step 3: Conclusion

From the above explanation, we can see that the fans with decorative wicker reed on their blades are less efficient than the ceiling fans with a smooth blade because the smooth bladecirculates more air than the wicker reed blade.

Thus, the fans with wicker reed on blades are quieter as compared to the ceiling fans with smooth blades.
