a number usually expressed as 1/2, 1/4, etc.; a part as distinct from the whole of anything; portion or section: He received only a fraction of what he was owed. Not to be confused with: friction –surface resistance to relative motion; the rubbing of one surface against another; dis...
Use the density formula to solve density example problems for density, volume, and mass. Related to this QuestionThe diesel tank on my tractor has a capacity of 13.0 gallons. Assume the density of petroleum diesel is 0.832 kg/L. a. When my tank is full, wh...
The mass of an ion of specified isotopic composition, which is calculated by summing the exact masses of the constituent atoms. The empirical formula of an ion can be deduced from the measured accurate mass of the ion if the ion mass is low enough to limit the number of formulaic possibilit...

In summary, to calculate the mass of gas in a tank, first measure the volume of gas in the tank. Next, determine the gas's density, which can vary with temperature and pressure. Finally, use the formula: mass = volume × density. Ensure that all measurements are in compatible units to...
Rao et al. (2020) improved the calculation formula of the transmissibility of cell connections in the original pEDFM, and established the connection between the fracture cells that are projected on the same matrix-cell interface, which eliminated the significant error of the original pEDFM in the...
fuel-air ratiomass transferfuel injection control system for internal combustion engine mass flow rate and measuring the mass flow of combustion air. the pulse length of the fuel injection is determined by the formula (i), where pd is the drop in air pressure generated by a venturi (32), ...
5.5 Effects of Adjacent Fluids: Hydrodynamic Mass Ship structures often border water or other fluids (e.g. fuel), either on one side (outer hull plates) or both sides (fuel tank bulkhead). Fluid immersion can be total or partial. If the structure borders a fluid, structure vibrations will...
