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 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)
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.
What do you mean by calorific value of fuels and how can you determine the colorific value of solid liquid and gas?
calorific value means the total amount of heat energy evolved when 1gm of the fuel is completely burnt. from the combustion equation find out enthalpy of combustion.then divide the molecular weight to that quantity.
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.
How do you do a conversion of Kwh to m3 gas natural?
To convert kilowatt-hours (kWh) to cubic meters (m³) of natural gas, you need to know the calorific value of the gas, which is typically around 9.5 to 11 kWh per cubic meter, depending on the gas composition. The conversion can be done using the formula: m³ of gas = kWh / calorific value (kWh/m³). For example, if the calorific value is 10 kWh/m³, then 100 kWh would equal 10 m³ of natural gas. Always check the specific calorific value for more accurate conversions.
How can one determine velocity using momentum?
To determine velocity using momentum, you can use the formula: momentum mass x velocity. Rearrange the formula to solve for velocity: velocity momentum / mass. By dividing the momentum by the mass of the object, you can calculate its velocity.
What is the process to write a formula for an insoluble compound?
To write a formula for an insoluble compound, you need to determine the charges of the ions involved and balance them to create a neutral compound. This involves using the crisscross method to determine the subscripts for each ion in the formula.
How can one determine velocity by using acceleration and time?
To determine velocity using acceleration and time, you can use the formula: velocity initial velocity (acceleration x time). This formula takes into account the initial velocity, acceleration, and time to calculate the final velocity.
How can one determine acceleration using time and distance measurements?
To determine acceleration using time and distance measurements, you can use the formula: acceleration 2 (distance / time2). This formula calculates acceleration by dividing the distance traveled by the square of the time taken to travel that distance.
How can one determine the volume using molarity and moles in a solution?
To determine the volume of a solution using molarity and moles, you can use the formula: volume (in liters) moles / molarity. This formula helps calculate the volume of a solution based on the amount of solute (moles) and the concentration of the solution (molarity).
