What is CFM Fan Calculator?
CFM Fan Calculator is a tool that helps to determine the required CFM capacity of a fan based on the power output and pressure. CFM stand for cubic feet per minute.
Here’s the formula for CFM Fan Calculator:
CFM = Power × 530 / Pressure / 2989
where Power is the power output of the fan in watts, Pressure is the pressure in pascals, and 530 and 2989 are conversion factors.
Example: Suppose a fan has a power output of 500 watts and operates at a pressure of 100 pascals. We can use the CFM Fan Calculator formula to determine the required CFM capacity of the fan:
CFM = 500 × 530 / 100 / 2989 CFM = 8.89
So the fan should have a CFM capacity of around 8.89 cubic feet per minute.
FAQs:
What is CFM in a fan?
CFM stands for cubic feet per minute, and it is a unit of measurement used to express the airflow rate of a fan. It measures the amount of air a fan can move in a minute.
How to measure the pressure of a fan?
The pressure of a fan can be measured using a manometer, which is a device used to measure pressure. It measures the difference in pressure between two points and gives the result in units such as pascals or inches of water.
What is the conversion factor in the CFM Fan Calculator formula?
The conversion factors used in the CFM Fan Calculator formula are 530 and 2989. The first factor converts the units of power output from watts to horsepower, while the second factor converts the units of pressure from pascals to inches of water.
