30 lb
If the tank is actually filled to the brim (tanks never are) the water would weigh 8.35lbs x 30gallons which is 250.5 lbs. To obtain an accurate total weight you would have to add in the weight of the sand/gravel substrate, and the rocks (decore) and the weight of the empty tank. Then you would subtract the weight of the top 1 inch or so that is always left empty.
a typical steel "30 pound" liquid propane tank weighs about 25-28 pounds empty. propane tank markings (on collar) propane weighs about 4.125 pounds per gallon and a "30 pound tank" will hold about 7.5 gallons so a full tank will weigh about 55 pounds or so. Typical recertification stamp: MM XXX YY E MM -> 2 digit recertification month XXX ->3 character Re-qualifier's registration number YY -> 2 digit recertification year E ->States the cylinder has been externally examined WC -> Water capacity of the cylinder. TW -> Tare weight of the cylinder (what the tank weighs empty) ICC, DOT, BTE, CTC or TC -> Specification number eg. TC4BA240 10 89 -> Date of manufacture (October. 1989)
. . . . 30 pounds
5 lbs, 6 ounces. as a side note, I couldn't use the last 26oz of freon.
$180.00 dollars $140 - assuming you start with an empty tank and finish with an empty tank.
about 36 pounds
250 LBS plus the weight of the tank
If your Sentra has a 13 gallon tank, probably 30-40 miles.
30 GAL. when compleatly empty.
my '96 cavalier sedan (233,000 miles) gets about 450 miles per tank if i run it completely empty, averaging 30 mpg.
You cannot use output pressure to tell how full a tank is. The pressure will remain constant until it's just about out of propane. You can use weight, if you know how much it weighs when empty, and when full - then it's just simple math.
There will be a TW on the side of the cylinder this is the tare weight the weight of the cylinder empty. (TW 27) would be an 27 pound empty cylinder. A full cylinder will weigh 30 pounds more than the tare weight.
