## How much fuel does a prime mover use?

Light commercial vehicle engines can use 2–3 L of fuel per hour idling, while prime movers use up to 4 L/h. If a vehicle is left idling, up to half the time the engine is running, it’s burning fuel with no benefit.

## How much fuel does a dump truck use in a day?

Dump trucks require a lot of fuel to operate. It’s the biggest operating expense you have in your daily operations. Some models are more fuel-efficient than others. Class 8 models will typically get around 3.2 gallons per hour for short hauls, and 6.2 for highway hauling.

**How much does a Kenworth T909 weigh?**

The T909 was rated at 130,000kg GCM and loads quite often come near that weight limit.

**Do heavier vehicles consume more fuel?**

A vehicle’s weight is an important factor in how much fuel it will consume. The heavier the vehicle, the more energy it needs to get moving. This means that reducing weight is a very effective way to lower a vehicle’s fuel consumption.

### What is the formula for fuel consumption?

Calculating consumption and range Simply note down the distance travelled since the last top-up and then take a note of how much fuel it consumed to travel that distance, then divide the litres used by the kilometres travelled and multiply by 100 to calculate consumption in litres/100km.

### How much fuel does a car use per hour?

The previous operation gives us the specific picture in relation to the cost of the total fuel consumed by the vehicle, however sometimes the variable “Fuel consumption per hour” is unknown and this could vary depending on the load factor received by the engine and of the type of operation that the machine performs.

**How much fuel does a 787 carry per hour?**

If you know the amount of fuel that the 787–900 carries for a given flight distance, and accounting for a 45 minute (0.75 hour) reserve, one can estimate what the SFC is. Enjoy the calculation. I will assume some 787 pilots will chime in with some real fuel requirements for given ranges.

**How to calculate the gas consumption per hour?**

In computational operations, a norm of 0.8-1 cubic meters is obtained – gas consumption per hour. This is provided that all burners are switched on at the same time. Scrupulously calculate the consumption of the hotplate for the month is possible thanks to the readings of the counters.
