The CFM to Voltage Calculator is a useful tool for converting airflow in cubic feet per minute (CFM) to voltage, based on pressure and frequency. It is commonly used in HVAC, electrical engineering, and automation systems where airflow and electrical signals are correlated.
Formula
The formula to calculate voltage from CFM is:
Voltage = (CFM × Pressure) / Frequency
Where:
- CFM (Cubic Feet per Minute) represents the airflow rate.
- Pressure (P) is the force exerted by the airflow.
- Frequency (F) is the electrical frequency in Hertz (Hz).
How to Use
- Enter the airflow value in CFM.
- Input the pressure value.
- Enter the frequency in Hertz.
- Click the "Calculate" button to get the voltage value.
Example
Suppose you have:
- CFM = 300
- Pressure = 5
- Frequency = 60
Calculation:
Voltage = (300 × 5) / 60
Voltage = 25 V
FAQs
- What is the purpose of a CFM to Voltage Calculator?
It converts airflow values into electrical voltage using pressure and frequency values. - Why do we need to convert CFM to voltage?
Some automation systems and sensors use voltage as an indicator of airflow rate. - What unit should frequency be in?
