Question

URGENT!!!!! I NEED THIS REALLY QUICK PLEEEAASE!!!

A team of students built an electric fan. They calculate that the fan’s efficiency is just 46%.

In 3–5 sentences, explain how they could improve the fan’s efficiency.

Answer 1

Step-by-step explanation:

Reduce the fan speed (to lower the power required).

Clean the fan blades to reduce the weight of the fan blades (and reduce the work required to move the blades).

Dehumidify the air to reduce the weight of the air the fan has to move.

Place a bucket of ice in front of the fan as a homemade AC unit. Cold air is less dense than warm or hot air and requires less work from the fan to circulate it.
