The sides and bottom of this rectangular slab of meat are insulated and the top surface is 254 mm by 254 mm square. If the surface of the meat is at -6.7°C,


Extracted text: predict the average heat-transfer coefficient to the surface. As an approxi- mation, assume that either Eq. (4.6-2) or (4.6-3) can be used, depending on the NRe L. Ans. h = 6.05 W/m² · K
