How do you calculate fuel consumption from horsepower?
Expressed as a formula it looks like this:
- Given Horsepower x .50 lb fuel/hp = lbs of fuel for given horsepower.
- 200 lbs/hr / 6.25 lbs/gal = 32 gph.
- BSFC . 50 / 6.25 = . 0800 gallons / horsepower / hour.
- OR.
- BSFC .70 / 6.59 = .106 gallons / horsepower / hour.
- 800 * .106 = 84.80 gph.
How much fuel does a four stroke engine burn?
This makes it important to know that gasoline weighs about 6.1 pounds per gallon and diesel fuel 7.2 pounds per gallon. On average, an in-tune four-stroke gasoline engine will burn about 0.50 pounds of fuel per hour for each unit of horsepower.
How much fuel does it take to make 300 hp?
So 24 gallons x 5.92 lbs = 142 pounds per hour to make 300 HP. If you burn 24 gallons of fuel per hour to make 300 HP, 142lbs/1 hour, you release 2,699,520 BTU’s of energy, (19,000x 142). 2,699,520/2545= 1061 HP. We wish, but the engine is only making 300 HP. This is where you can tell if the numbers someone is telling you are real or not.
How many gallons per hour does a 150 horse engine burn?
It’s just not as accurate as the formulas above. The result represents the approximate gallons per hour the engine will burn at wide-open throttle. For example, a 150-horse engine will use about 15 gallons per hour.
How much fuel does a gasoline engine burn?
On average, an in-tune four-stroke gasoline engine will burn about 0.50 pounds of fuel per hour for each unit of horsepower. Likewise, a well-maintained diesel engine burns about 0.4 pounds of fuel per hour for each unit of horsepower it produces.
How much fuel does a boat burn per hour?
At full throttle and averaged across makes and models, those engines burn about one gallon of fuel per hour for every 10 horsepower (hp). Generally, it takes about 2.5 hp to plane 100 pounds for a near flat-bottomed boat. Other shapes, such as deep-v hulls, require more power.
