process : Calculating with Process 19AG16i17 process : brewerslabEngine rev 2012-10-09 process : changes since 2011-09-14 process : - conversion to use Gql datastore rather than pickle process : - removed ingredients against activities never used so far process : - found potential bug with checkStockAndPrice and kegs process : - now using implicit caprequired/co2required process : changes since 2011-04-15 process : - waterRequirement changes to better include FV deadspace process : - waterRequirement ignore hop wastage if boilder deadspace is greater process : key assumptions process : - hops not scaled based on topup assumed marginal process : ( need some calculation for this as big assumption) boilWaste: Adding 1.25 for wastage in the boiler boilWaste: Adding 1.25 for wastage in the boiler boilWaste: batch size adjusted to 28.50 to account for wastage in boiler boilWaste: batch size adjusted to 30.0 to account for wastage in fermentation bint calcferm : Calculating expected gravity calcferm : fermentable: 340.0gm Honey calcferm : hwe: 291.84 extract: 76.0 calcferm : contribution = 3.30678589353 calcferm : 3.30678589353 = 0.34 * 291.84 / 30.00666 calcferm : fermentable: 200.0gm Torrified Wheat calcferm : hwe: 299.52 extract: 78.0 calcferm : contribution = 1.99635680879 calcferm : 1.99635680879 = 0.2 * 299.52 / 30.00666 calcferm : Including in Mash Gravity calcferm : fermentable: 5000.0gm Tipple calcferm : hwe: 315.648 extract: 82.2 calcferm : contribution = 52.5963236162 calcferm : 52.5963236162 = 5.0 * 315.648 / 30.00666 calcferm : Including in Mash Gravity calcferm : uncorrected gravity for grain 1.055 calcferm : correcting gravity based on mash efficiency of 71.0 % calcferm : estimated_gravity_mashedgrain = 38.7608031017 calcferm : 38.761 = 57.899 * 0.71 calcferm : 1.039 = 1 + (38.761/1000) calcferm : estimated_gravity_nonmashedgrain = 3.30678589353 calcferm : estimated_gravity = 38.761 + 3.307calchops : Calculating Tinseth Hop Calculation calchops : http://www.realbeer.com/hops/research.html calchops : setting volume for hops calculations to 38.01 (was 30.01) result : hop_utilisation = 0.0000 for 1.0421 @ 0.001 m tinseth : 0.0000 = 1.1306 * 0.0000 tinseth : bigness_factor = 1.1306 tinseth : 1.1306 = 1.65 * 0.000125 ^ ( 1 + estimated_gravity / 1000 ) tinseth : 1.1306 = 1.65 * 0.000125 ^ (1.0421 -
