Oven, 200 °C
In Betty's Crocker's cookbook, it is stated
that it takes 3 hours and 45 minutes to roast a
0.92 kg rib initially at 4.5 °C in an oven
maintained at 200 °C for a well-done cooked
meat status. It is recommended that a meat
thermometer be used to monitor cooking. The
Rib, 4.5 °C
well-done cooked meat status is achieved
when the center of the thickest part of the rib registers 180.5 °C. The rib can be treated as a
homogeneous sphere with the following properties (p=1200 kg/m², Cr= 4.1 "kg.K, k=0.45
W/m.K and a= 0.91×10-7 m²/s).
1. Determine the heat transfer coefficient at the surface of the rib
2. BONUS: If the roast rib is to be set on the counter for about 15 minutes before it is
sliced, it is recommended that the rib be taken out of the oven when the thermometer
registers about 4 °C below the indicated value because the rib will continue cooking even
after it is taken from the oven. Do you agree with this recommendation?
