A generator’s runtime is determined by the size of its fuel tank and its fuel consumption rate. The formula to calculate the runtime is straightforward: [ text{Runtime} = frac{text{Tank Size}}{text{Fuel Consumption Rate}} ].
Fuel Consumption Rate = the rate at which the generator consumes fuel, typically measured in gallons per hour (GPH) or liters per hour (LPH).
For example, if a generator has a 20-gallon tank and consumes fuel at a rate of 5 GPH, it will run for [ frac{20}{5} = 4 ] hours.
