Outstanding effort, fellas! I have a free Beer calculator online that may help you calculate the following important aspects of home-brewed beer: the number of main ingredients (water and malt), the needed density and color of the drink, hop bitterness, and wort carbonation. The first calculator will tell you how much water you need to add to the wort, while the second will tell you how much effort you need to do to get the required density. The second calculator will be used to calculate the density of the wort in the new volume.
