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.
Heavy oil weighs more than light oil. To determine the weight, we need to know the density of the oil, which is given as degrees API. Density in pounds p â¦ er gallon = 141.5/(131.5 + API) *62.4 So a heavy oil. (10 degrees API for example) , has a density of 62.4 pounds per gallon, and one gallon weighs 62.4 pounds. Gallon = 3.7854118 liters Considering a liter weighing 1 Kg (water for instance), then a gallon weighs 3.78541 â¦ 18 Kg. Water weights 8.328 lbs. per gallon. since while freezing water expands slightly a gallon of ice will be just a few onces less or approximately 8 lbs.
