1. What is the Firman Tri Fuel Generator Run Time Calculator?

This calculator estimates how long a Firman tri-fuel generator will run based on the amount of fuel available, the current load, and the generator's fuel consumption rate.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Fuel\ Amount \) — Amount of available fuel (gallons)
• \( Load \) — Current load as decimal (0-1, where 1 = full load)
• \( Consumption \) — Fuel consumption rate (gallons/hour/kW)

Explanation: The equation calculates run time by dividing the available fuel by the product of load and consumption rate.

3. Importance of Run Time Calculation

Details: Accurate run time estimation helps in planning fuel needs, especially during emergencies or extended outages when generator operation is critical.

4. Using the Calculator

Tips: Enter fuel amount in gallons, load as decimal (0.5 for 50% load), and consumption rate in gallons/hour/kW. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical consumption rate for Firman generators?
A: Consumption varies by model and fuel type, but typically ranges from 0.08 to 0.15 gallons/hour/kW under full load.

Q2: Does fuel type affect the calculation?
A: Yes, consumption rates differ for gasoline, propane, and natural gas. Use the appropriate rate for your fuel type.

Q3: How accurate is this calculation?
A: It provides a good estimate but actual run time may vary based on generator condition, altitude, temperature, and other factors.

Q4: Should I include reserve fuel in my calculations?
A: Yes, it's recommended to maintain at least 20% reserve fuel beyond your calculated needs.

Q5: How does load affect run time?
A: Higher loads significantly reduce run time. Running at 50% load typically provides more than double the run time of full load.
