1. What is the BTU Pipe Size Calculator?

The BTU Pipe Size Calculator for propane systems determines the appropriate pipe size based on required BTU capacity, pipe length, and pressure drop considerations for low pressure propane applications.

2. How Does the Calculator Work?

The calculator uses standard pipe capacity tables:

Where:

• Capacity — Required BTU per hour
• Size — Pipe diameter in inches
• Length — Total pipe run in feet

Explanation: The calculation accounts for pressure drop along the pipe length and ensures adequate gas flow for appliance requirements.

3. Importance of Proper Pipe Sizing

Details: Correct pipe sizing is crucial for safe and efficient propane system operation. Undersized pipes can cause pressure drops and appliance malfunction, while oversized pipes are unnecessarily expensive.

4. Using the Calculator

Tips: Enter the required BTU capacity, proposed pipe size in inches, and total pipe length in feet. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What pressure does this calculator assume?
A: This calculator is designed for low pressure propane systems, typically 11 inches water column (0.4 psi).

Q2: How does pipe length affect capacity?
A: Longer pipe runs increase friction loss, reducing the available capacity. The calculator adjusts for this automatically.

Q3: What are common pipe sizes for propane?
A: Common sizes include 1/2", 3/4", 1", 1-1/4", and larger for main lines serving multiple appliances.

Q4: Should I include fittings in the length calculation?
A: Yes, add equivalent length for fittings. Typically add 20-50% to the measured length for standard fittings.

Q5: Is this calculator suitable for high pressure systems?
A: No, this calculator is specifically designed for low pressure propane applications. High pressure systems require different calculations.
