Scale-Up in Nature

Turkey Cooking time Predicted cooking time Cooking time Predicted cooking 

Before passing judgment on our grandmother s recipe, we need to relate the area of the turkey to its mass. Assuming that the turkey is roughly a sphere, then 

Although with this equation we are unable to predict the required cooking time for our turkey, we can use (10.31) to extrapolate the cooking time from one size to a larger or a smaller size. Let us use as a reference the cooking time for a 20 [lb] turkey (Table 10.3). Then we can calculate the cooking time for 14 and 28 [lb] and compare with the data reported in our grandmother s table (Table 10.4). 

Multiscale. As presented in Chap. 4, the loms plant has inspired the development of materials that are repellent to water, and likewise the stmcture of honeycombs has inspired stracmral and mechanical engineers, architects, and artists. As expressed by Coppens (2003), in the chemical and bioprocess engineering fields, there are big differences between engineers solutions and namre s solutions to similar problems. One aspect of nature that could benefit our field is the way it stretches the gap at large scale, which is a big problem for chemical and bioprocess engineers (Coppens 2005).
