1. Bunker Calculation: Bunker terms to fuel oil in the maritime industry. Bunker quantity calculation is the most important calculation which every marine engineer should be familiar with throughout his career. Bunker fuel, being a highly valued product, has to be very carefully and accurately calculated for determining the quantity.

Energy density is the amount of energy that can be released by a given mass or volume of fuel. It can be measured in gravimetric energy density (per unit of mass) or volumetric energy density (per unit of volume). Gravimetric energy density is relevant when comparing the energy efficiency of fuels. At the same time, volumetric energy density is ...

Density - ρ - and specific volume of some commonly used fuels: Note 1) Diesel fuels are in USA broken up into 3 different classes: 1D, 2D and 4D. The difference between these classes depends on viscosity and boiling point ranges . 4D fuels tend to be used in low-speed engines. 2D fuels are used in warmer weather and are sometimes mixed with 1D ...

Station capacity determines the quantum of coal to be handled by coal handling plant and thus the capacity of coal unloading system, crushers, coal conveying system etc. Generally for unit size of 500 MW and above, one coal handling plant is provided to cater for two units. Coal conveying system may cater to maximum three units to limit the ...

considered to represent a maximum and minimum sequestration capacity for coal. The sorption values from Krooss et al. (2002) are given in cubic centimeters of CO2 per gram of coal at 15°C and 1 atm (1.01325 bars). The volume of CO2 was converted to a unit mass using the density of CO2 (1.86 kg/m 3) at 15°C and 1.01325 bars (Krooss et al., 2002).

Bunker fuel also known as the bunker is any fuel used for powering a ship. The term has its roots back in the days when the primary source of power for the ships was coal. The coal was stored in a …

Environmental emission of carbon dioxide CO 2 when combustion fuels like coal, oil, natural gas, LPG and bio energy. To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7.

To calculate the volume of a cylinder of length or height h and circular cross-section of radius r, use this formula: V=pi times r^2 times h. When measuring a closed container from the outside, you need to subtract the wall thickness (t) from the radius and the lid/base thickness from the height. The capacity formula then becomes (using a ...
