The brewing process involves 4 steps. Boiling, Fermenting, Filtering and Kegging. The batch size is 100 gallons for the boil and fermentation tanks. Process times for the different steps are Boiling: 8 hours/100 gal, Fermenting: 15 days/100 gal, Filtering: 10 gal/hour, Kegging 10 min/5 gal. In order to improve the productivity they decide to introduce a holding tank between the fermentation and filtration steps. They are able to drain the fermentation tank at a rate of 30 gal/hour. WIP Boil Ferment Filter Keg What is the minimum WIP tank size they need? (Round your answer to the nearest 10 gallons) Assume 24 hours/day
