Electric Fan Cfm Calculator

When a fan is set to its maximum speed the cfm is calculated by utilizing both the volume of air and the rate at which the fan blades move.

Electric fan cfm calculator.

Merely it can also be termed as airflow. Rise f δt volts amps. Cfm volts x amps x 3 412 δt x 1 08 δt f volts amps. Bathroom vent fan cfm cubic feet per minute calculator.

Centrifugal blower fan squirrel cage blower. 1 250 cfm for a 4 cylinder 2 000 cfm for a 6 cylinder 2 500 cfm for a 8 cylinder. Run the fan for 15 to 20 minutes after showering or bathing to expel all the excess moisture. The calculator is a versatile energy management tool which accepts measured current full load amps or rated horsepower inputs.

This would be 3 1416 x 0 25 square feet x 800 feet 628 32 cubic feet per minute at 1200 rpm. Obviously an 800 horsepower engine will need more cooling than a 400 horsepower version regardless of the cylinder count but this basic guidance will get you started. Fan cfm calculator 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. Cfm btu s δt x 1 08 input.

Enter any two parameters to get the third. With the motor load calculator you can quickly estimate annual energy use and cost for any electric motor. 1 250 cfm for a 4 cylinder 2 000 cfm for a 6 cylinder. Calculate the cfm volumetric flow of air at 1 200 rpm.

A further note is that engines that are 5 0 liter 302 cubic inches or larger should use an electric fan with 2 800 or more cfm. Existing static pressure in. As a general rule of thumb follow these minimum cubic feet per minute cfm ratings when using an electric fan as the primary cooling source on a basic engine. 1 electric heat temperature rise method.

Basic fan laws existing flowrate cfm. Cfm or its elaboration cubic feet per minute is referred to as the amount of air that can be moved per cubic feet in a minute. Cfm stands for cubic feet per minute so an electrical fan with a 1 500 cfm rating will push 1 500 cubic feet of air per minute. 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.
