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)
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)
Integers are placed in front of the formula or a chemical symbol for and element.
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).
x = [ -b ± √(b2-4ac) ] / 2a Using this formula you get 2 roots for + and -
To determine the number of pairs for 6 nodes using a formula, you can use combination formula. In this case, the formula would be nC2, where n represents the number of nodes. Substituting n=6, the formula becomes 6C2, which is equal to 15. Therefore, there would be 15 pairs of nodes for 6 total nodes.
Completing the square is advantageous in several situations:usually, it requires fewer steps than the quadratic formula, reducing the potential for error.it allows you to determine the exact value of the answer instead of a decimal approximation.it allows you to determine imaginary solutions.
The average speed of an moving object is determined by using the formula velocity=distance/time or v=d/t.
Heatrate is the term used in power industries to check how efficiently the plant is running. its unit is kilo calories per kilowatt hour..= Kcal/Kwh or in a shortcut method, the HR can be directly calculated by using the formula = Specific fuel consumption * Calorific value
The displacement method is used to determine volume. However, if you know the density, the displacement test can give volume, which is used to work out mass by the formula m = dV
