After traveling around the world making wine for several years, you decide to settle in California and open up a winery that specializes in Syrah. From your experience at crush positions in Australia, you decide to purchase several rotary fermentors with gal working volumes. Because you don't have much money to start, you go with a lowcost stainlesssteel tank fabricator that has not made one of these tanks before, but is interested in starting. Therefore, you need to give him a lot of information on the design. The basic geometry is shown in the figure below.
a You plan to ferment your Syrah at a maximum temperature of To maintain this temperature, you are hoping to use a municipal water source that is typically at during the late September harvest. The temperature at the outlet of the jacket should not exceed At your planned fermentation temperature, your experience tells you that you should have a maximum sugar utilization rate of about Brix per day. Assuming an overall heat transfer coefficient of will you have enough heat transfer surface area if only the bottom half of the fermentor is jacketed? Btuhr gal WL
b What is the necessary volumetric flow rate of cooling water through the jacket? Would it be reasonable to use a dimpled jacket with this type of flow rate? The heat capacity and density of the cooling water are and respectively.
