The SCFH to psi Calculator is an essential tool that helps convert the flow rate of gases, measured in Standard Cubic Feet per Hour (SCFH), to pressure in Pounds per Square Inch (psi). This conversion is vital for applications involving gas flow through pipelines, regulators, and other systems where pressure readings are necessary for safety and operational guidelines.
Why Use This Calculator?
- Precision: Ensures accurate conversions critical for system design and safety compliance.
- Efficiency: Saves time by providing quick calculations without manual conversion needs.
- User-Friendly: Simple input and output format that can be used by professionals without advanced technical knowledge.
Formula of SCFH to PSI Calculator
To convert SCFH to psi, use the following formula:
Where:
- psi is the output pressure in pounds per square inch,
- SCFH is the input flow rate in standard cubic feet per hour,
- SG is the specific gravity of the gas.
This formula accounts for the specific gravity of the gas, which indicates how dense the gas is compared to air (SG of air = 1.00).
Table of General Terms
Here’s a quick reference table for converting SCFH to psi for different gases:
| Gas Type | Specific Gravity (SG) | Example SCFH | Calculated psi |
|---|---|---|---|
| Natural Gas | 0.60 | 100 | 1.46 |
| Air | 1.00 | 100 | 2.44 |
| Propane | 1.50 | 100 | 3.66 |
Example of SCFH to PSI Calculator
Converting Natural Gas from SCFH to psi:
Given:
- Flow rate = 100 SCFH
- Specific Gravity of Natural Gas = 0.60
Using the formula:
- psi = (100 SCFH * 0.60 SG) / 40.96 = 1.46 psi
This result means that 100 SCFH of Natural Gas at a specific gravity of 0.60 results in a pressure of 1.46 psi.
