For a simple estimate of the changes in ΔH, one can use the constant c¯p formula: (9.64)ΔH=ΔH0+∑nPic¯pPi(TPi−T0Pi)−∑nRic¯pRi(TRi−T0Ri). Example 9.2 The standard enthalpy of formation of water vapor is −241.8 MJ/kmol. What is the enthalpy of formation when...

Using a graph or derivates are how to calculate the instantaneous and average rate of changes. The formula for calculating the average rate of change is: {eq}(f(b) - f(a))/(b - a) {/eq} The change in y values divided by the change in x values. The formula for how to calculat...
How do you find the average rate of change from a graph? To find the average rate of change from a graph over a specified interval, simply find the coordinates of the points at each end of the interval, and use those values in the slope formula to find the average rate of change betw...
Note that the use of this formula caps the highest obtainable frequency to the 1-year return period. Therefore, by construction that is going to be the highest future frequency projected by our approach, even if some locations could experience present-day 100-year ESL events more often than on...
Ultimately I am trying to put together a formula that will calculate a weighting value for each row. This will be represented by a weighting value (W1) applied to the % change in average values for the last 12 months (P1) as compared to the 12 months before that (P2...

This formula can also be written as: R = (D2- D1)/T where: R = rate of change D = distance (or some other variable) measured at the beginning and end of the period T = the time it took for that change to occur In finance, the calculation for ROC can also be computed as a...
