Effect of size on heat processing meat. an autoclave held at 121.1°c is being used to process sausage meat 101.6 mm in diameter and 0.61 m long which is originally at 21.1°c. after 2 h the temperature at the center is 98.9°c. if the diameter is increased to 139.7 mm, how long will it take for the center to reach 98.9°c? the heat-transfer coefficient to the surface is h = 1100 w/m^2 * k, which is very large, so the surface resistance can be considered negligible. (show this.) neglect the heat transfer from the ends of the cylinder. the thermal conductivity k = 0.485 w/m * k.

Afan that can provide air speeds up to 60 m/s is to be used in a low-speed wind tunnel with atmospheric air at 35 c. if one wishes to use the wind tunnel to study flat-plate boundary layer behavior up to reynolds numbes of re 10, what is the minimum plate length that should be used? at what distance from the leading edge would transition occur if the critical reynolds nurnber were rer, e = 5 × 105?
