1. What is PSI to CFH Conversion?

The PSI to CFH conversion approximates the cubic feet per hour (CFH) flow rate from pounds per square inch (PSI) pressure measurements. This is commonly used in gas flow calculations.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( CFM \) — Cubic feet per minute (ft³/min)
• \( CFH \) — Cubic feet per hour (ft³/hour)

Explanation: The formula converts flow rate from minutes to hours by multiplying by 60.

3. Importance of CFH Calculation

Details: CFH calculations are essential for sizing gas pipes, determining appliance gas consumption, and ensuring proper ventilation in gas systems.

4. Using the Calculator

Tips: Enter CFM value in ft³/min. The value must be greater than 0 for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this conversion?
A: This provides an approximate conversion. Actual flow rates may vary based on specific gas properties and system conditions.

Q2: What's the difference between CFM and CFH?
A: CFM measures flow per minute while CFH measures flow per hour (1 CFH = 1/60 CFM).

Q3: When should I use this conversion?
A: Use when you need to convert between minute and hour flow rates, particularly in gas flow applications.

Q4: Are there limitations to this conversion?
A: This is a simple time conversion and doesn't account for pressure drops, temperature effects, or gas composition.

Q5: Can I use this for liquid flow?
A: While the time conversion works, liquid flow calculations typically require additional factors like specific gravity.
