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.
One gallon weighs from 5.8 to 6.5 pounds, depending on the temperature when yo â¦ u weigh it. Water holds similar weight properties as gasoline, so you may wish to test this by weighing one gallon of hot water and one gallon of cold water and taking the average. Don't measure, pour or heat gasoline!!Gasoline wegihs 6.08 pounds per gallon, diesel weighs an average of 7.1 pounds per gallon, water weighs 10.0 pounds per gallon.
