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.
