An engine dynamometer measures torque (lb-ft), not mechanical energy (ft-lb); and an engineâs âtimeâ is expressed in revolutions per minute (rpm). Since 6.28 ft-lb of work is about equal to 1 lb-ft of torque, you can substitute the eqautions in Figure 2.
DEF weighs approximately 9 lbs per gallon. Compared to diesel fuel at approx 7.05 lbs and gasoline at an average of 6.19 lbs, DEF is a relatively heavy product.ow much DEF can I haul? With DEF weighing in at around 9lbs per gallon, we estimate that with a tandem axle truck tank you will be able to haul just over 3000 gallons in most states. For trailers the capacity will be around 5,000 gallons.
A US gallon of water weighs in at 8.33 pounds. The weight of the volume of water you displaced is equal to your own weight. For example, if you displaced 20 US gallons, then 8.33X20= 166.6 pounds. The second way: One US gallon of water weighs in at 8.33 pounds. A paint can is a known volume of 1 gallon.his wasn't a stupid question AT ALL! There actually is a way & I use it! Initially you do have to use a scale, but only once! You weigh yourself, then start counting calories consumed and burned and they have calculators that can tell you your deficit.
