Ceiling Fan Wind Speed Calculator

The wind speed variable is expressed in mph and is computed based on the cfm reported by the manufacturer along with the width of the fan plus 8 which is the width of the cylinder employed for testing ceiling fan cfm.

Ceiling fan wind speed calculator.

To feel the more powerful wind speed you will need to be directly underneath the ceiling fan or at least very nearby and not far from the tips of the fan blades. Unless you like replacing your ceiling fan every few months or feeling as if you re in a tornado choose a ceiling fan that is proportionate to the room size. Whether exhausting air or bringing fresh air into a structure the calculation produced should help to figure out the size of fan s required to accomplish the air exchanges needed. Based on this new trend we recommend this.

Wind speed from a ceiling fan is sort of the same as the breeze between the two buildings that created the wind tunnel effect. Choose the largest fan with the highest wind speed that will fit into the space without overwhelming it visually. The fact is smaller blades put less drag on the motor so it spins at a higher rpm moving the air much faster creating a stronger breeze in the area directly beneath the fan. Volume of the space in cubic feet 60 minutes in an hour cfm of the fan selected the number of fans selected that are required to achieve one 1 air turn in one 1 hour.

Ceiling fan size recommendation calculator this calculator is based on the current trend to use larger fans in smaller rooms. After selecting the fan size you are going to use apply the following formula. Ceiling fan airflow and efficiency are often overlooked but the amount of air your fan moves each minute impacts the level of performance. Wind speed is calculated by measuring how quickly on average air can get from the ceiling fan blades down to the floor and is commonly reported in miles per hour mph.

A large ceiling fan in a small room will create an uncomfortable amount of airflow. This really is why i divised the wind speed variable calculator which supplies a means of computing the airflow intensity which i ve termed wind speed variable providing you the capability to compare different size fans with various cfm. An instrument called an anemometer is used to calculate the wind speed by placing it in the direct flow of the wind allowing the propeller or cups to spin through the wind. Five factors work together to determine the airflow and efficiency of a ceiling fan.

This fan calculator is typically used to calculate the cfm or cubic feet per minute of air exchange that may be desired in a building. Use our exclusive ceiling fan wind speed calculator to quickly compare the performance between ceiling fans and determine how much cooling breeze you might expect. Blade pitch blade shape and size rpm height from ceiling and motor size. Aug 11 2017 ceiling fan wind speed is the most important consideration when shopping for a ceiling fan.
