1. What Is BTU/hr Conversion?

The BTU/hr conversion calculates the energy rate from gas flow measurements. It converts volumetric flow rate (cubic meters per hour) to energy output (BTU per hour) using the heating value of the gas.

2. How Does The Calculator Work?

The calculator uses the conversion formula:

\[ BTU/hr = m³/hr × 35,315 × Heating Value (BTU/ft³) / 35.315 \]

Where:

\( m³/hr \) — Gas flow rate in cubic meters per hour
\( Heating Value \) — Energy content per cubic foot of gas (BTU/ft³)
\( 35,315 \) — Conversion factor from cubic meters to cubic feet
\( 35.315 \) — Simplified conversion factor

Explanation: This formula converts the volumetric flow from metric units to imperial units and multiplies by the energy content to determine the total energy output rate.

3. Importance Of Energy Rate Calculation

Details: Accurate energy rate calculation is essential for sizing heating equipment, calculating fuel consumption, determining system efficiency, and estimating operating costs for gas-fired systems.

4. Using The Calculator

Tips: Enter gas flow rate in cubic meters per hour and the heating value in BTU per cubic foot. For natural gas, the typical heating value is approximately 1000 BTU/ft³. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical heating value for natural gas?
A: Natural gas typically has a heating value around 1000-1100 BTU/ft³, but this can vary by location and gas composition.

Q2: Why convert from m³/hr to BTU/hr?
A: This conversion allows engineers and technicians to determine the actual energy output of gas systems, which is more useful than volumetric flow for system design and efficiency calculations.

Q3: Can this calculator be used for other gases?
A: Yes, simply input the appropriate heating value for the specific gas type (propane: ~2500 BTU/ft³, butane: ~3200 BTU/ft³).

Q4: How accurate is this conversion?
A: The conversion is mathematically precise. Accuracy depends on the accuracy of your flow measurement and the heating value used.

Q5: What are common applications for this calculation?
A: HVAC system sizing, boiler capacity determination, industrial process heating, gas turbine performance, and energy consumption analysis.
