Unformatted text preview: The efficiency is defined as the ratio of the minimum possible amount of energy that must be removed from the dough ball to bring it to a uniform temperature of T freeze to the actual amount of heat removed from dough ball at the time identified in (c). You may want to use the function sphere_Q in EES to do this problem. e.) You would like to improve the processing time and are looking at blowers that will increase the heat transfer coefficient by increasing the velocity of the air. Plot the processing time (i.e., the answer to (c)) as a function of the heat transfer coefficient. At high values of h your plot should asymptotically approach a constant value; explain this behavior. f.) Overlay on your plot from (e) the efficiency as a function of h . Explain the shape of your plot....
