Mass, Weight, Density or Specific Gravity of Different Metals

For example, beryllium has a specific gravity (sg) of (1840 kg/) (see table below) As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also lbs/ (pounds per cubic foot) and if we know that a sample of alumimium has a sg of then we can calculate that its density is x = 156 lbs/

How to Calculate Gas Consumption in a Gas Burner | Hunker

 · Note that this is a rating of gas consumption, not the burner's output. One gallon of propane contains 91,500 Btu. Divide this number by the burner's per-hour rating to determine how long the burner can run 1 gallon of propane. For example, if the burner's Btu per-hour rating is 25,000: 91,500 divided by 25,000 =

Parts per Million - ppm - Engineering ToolBox

Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, Parts per million is the molar mass, volume or mass ratio between the pollutant component and the is defined as. ppm = 1,000,000 c / s = 10 6 c / s (1). where . c = molar mass, volume or mass of component (mole,

Density of metals

If it were changed to gold, it would weigh about 161 lb (19 gallons of water)! Did you notice that copper is denser than iron? A cubic foot of iron would weigh 491 lb. A cubic foot of copper would weigh 559 lb. Silver is even denser than copper, at 655 lb for a cubic foot. Gold is really heavy at 1206 lb for a cubic foot.
