Yes. Not sure on the exact weights (as it depends on size of tank and pressure of the gas) but you can tell a definite weight difference between an empty and full tank because the compressed air does have a weight
A full cylinder is heavier than empty. The cylinder is filled by weight.
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.
Normally it is done by weight. The empty cylinder weight is known and the weight with CO2 is taken and the CO2 weight is found.
Gas cylinders weigh about the same whether full or empty.
There is a fair amount of variation, but the standard small 16.4oz (1 lb) propane cylinder usually weighs just about a pound when empty (Tare weight, or the weight of the container itself). It is then usually charged with 16oz (by weight) of liquid propane for a total of around 32iz (2 lb).In SummaryTare Weight: 16oz (weight of the container/bottle)Net Weight: 16oz (weight of the liquid propane fuel)Gross Weight 32oz (weight of a full bottle)or in more practical terms, the closer your bottle is to weighing 1 lb, the closer you are to empty.
Presumably one is empty while the other one is full.
It should weigh 45kg + the TARE weight of 36.6kg for the bottle = 81.6kg when full. The WC (water capacity) of the bottles are 109.8kg and LPG weighs 41% of water = 45kg. This is a good check to see if you are being ripped off by your gas supplier.
All propane cylinders will have a TW stamped in the valve protection ring. The tare weight or TW is the weight of the cylinder empty. TW 18 would be a 18 pound empty cylinder. If you weigh a TW 18 cylinder on a bathroom scale, and it weighs 28 pounds there would be 10 pounds of propane remaining in the cylinder.
An empty gas container actually weighs less than a full container.
Curb weight, 3210 lbs. Gross weight, 4718 lbs.
It's a complex formula - taking into consideration the weight of the empty car, the weight of the cable connecting the car to the weight and the weight of a 'full' car.
If the master cylinder reservoir is empty, you have a leak somewhere. If the master cylinder reservoir is full, the master cylinder is bad.
