What is the cylinder fill weight for a 30 lb. DOT cylinder with a tare weight of 15 lbs.?

35 lbs.
40 lbs.
45 lbs.
50 lbs.

The correct answer is: 45 lbs.

To determine the cylinder fill weight for a 30 lb. DOT cylinder with a tare weight of 15 lbs., it's essential to understand the concepts of tare weight and total cylinder weight. The tare weight is the weight of the cylinder when it is empty, which, in this case, is given as 15 lbs. The total weight of a fully filled cylinder is 30 lbs., which includes both the weight of the gas contained and the tare weight of the cylinder itself. To find the fill weight (the weight of the gas), you subtract the tare weight from the total weight: Fill Weight = Total Weight - Tare Weight Substituting the known values: Fill Weight = 30 lbs. - 15 lbs. = 15 lbs. However, the question asks for the total weight of the filled cylinder, not just the fill weight. When asking for cylinder fill weight, it's crucial to note that the total weight of the filled cylinder should be taken into account when referencing the tare weight. Thus, if we consider the total weight for a fully filled cylinder, you add the fill weight to the tare weight: Total Weight (Full) = Tare Weight + Fill Weight From the above: Total Weight (Full) = 15
