Explain the experiment to determine the calorific value of fuel using dulong's formula?
To determine the calorific value of a fuel using Dulong's formula, you would first measure the mass of the fuel and then burn it completely in a calorimeter, which measures the heat released during combustion. From the heat released, the calorific value can be calculated using Dulong's formula, which takes into account the carbon, hydrogen, and sulfur content of the fuel. This formula is Calorific Value (CV) = 337(Carbon%) + 1442(Hydrogen%) + 93(Sulfur%) – 87(Ash%).
Why is nitrogen not involve in dulong's formula?
Nitrogen is not included in Dulong's formula for calculating the specific heat capacity of solids because nitrogen is a diatomic gas at room temperature and does not typically contribute significantly to the specific heat capacity of solids. Dulong's formula focuses on elements in their solid form where nitrogen is a gas.
How many tj are in 1000 cubic m of natural gaz?
Assuming "tj" refers to terajoules, we need to know the calorific value of the natural gas in order to calculate how many terajoules are in 1000 cubic meters. The calorific value can vary depending on the composition of the gas. Once you have the calorific value, you can convert the volume of the gas to energy in terajoules using the formula Energy (TJ) = Volume (cubic meters) * Calorific Value (MJ/m³) / 1000000.
How do you convert GCV to calorie?
GVC stands for gross caloric value. Gross calorific value may be converted to net calorific value by using the following equation, Net calorific value = Gross calorific value - (10.02 x Percent Moisture)
What do you mean by calorific value of fuels and how can you determine the colorific value of solid liquid and gas?
The calorific value of a fuel is a measure of the amount of heat energy released when it is burned. The calorific value of solid, liquid, and gas fuels can be determined using calorimetry, where the fuel is burned in a controlled environment and the heat released is measured. This heat measurement can then be used to calculate the calorific value of the fuel.
How do you convert gross calorific value to net calorific value?
You can convert gross calorific value (GCV) to net calorific value (NCV) by subtracting the latent heat of vaporization of water formed during combustion from GCV. The equation for this is NCV = GCV - 2.5 x (9 x % H2 - % O2), where % H2 is the percentage of hydrogen in the fuel and % O2 is the percentage of oxygen in the fuel.
What Process of using empirical formula and the value for experimental molar mass to determine the molecular formula?
The empirical formula is the formula in its most simplified terms. The molecular formula is how many moles there actually are (the empirical formulat multiplied by a factor).
How do you determine mass using momentum and velocity?
You can determine mass using momentum and velocity by using the formula: momentum = mass x velocity. Rearrange the formula to solve for mass as mass = momentum/velocity. Plug in the values for momentum and velocity to calculate the mass.
How To Determine The Roots Of Quadratic Function?
x = [ -b ± √(b2-4ac) ] / 2a Using this formula you get 2 roots for + and -
How to calculate ncv from gcv of coal?
Net calorific value (NCV) can be calculated from gross calorific value (GCV) of coal using the formula: NCV = GCV - (0.09 * moisture content) for lignite and sub-bituminous coals, or NCV = GCV - (0.07 * moisture content) for bituminous and anthracite coals. The moisture content is usually provided on the coal analysis sheet.
What ratio can you determine using the coefficient in a chemical formula?
The ratio of different elements present in a compound can be determined using the subscripts or coefficients in a chemical formula. These coefficients represent the relative number of each type of atom in the compound.
Explain that different fuels have different calorific value and the consequences of this?
Different fuels have varying calorific values, which represent the amount of energy they can produce when burned. Fuels with higher calorific values can generate more energy per unit mass compared to fuels with lower values. This can impact efficiency, environmental impact, and cost of energy production using these fuels.
