Q4) A long steel bar 5 by 10 cm is initially maintained at a uniform temperature
of 250 "C. It is suddenly subjected to a change such that the environment
temperature is lowered to 35 °C. Assuming a heat-transfer coefficient of
23 W/m² °C, use a numerical method to estimate the time required for
the center temperature to reach 105 °C. Check this result with a
calculation using the Heisler charts.

Model the egg as a sphere with radius of 2.3 cm that has properties similar to water with a density of = 1000 kg/m3 and thermal conductivity of k = 0.606 Watts/(mC) and specific heat of c = 4182 J/(kg C). Suppose that an egg is fully cooked when the temperature at the center reaches 70 C. Initially the egg is taken out of the fridge at 4 C and placed in the boiling water at 100 C. Since the egg shell is very thin assume that it quickly reaches a temperature of 100 C. The protein in the egg effectively immobilizes the water so the heat conduction is purely conduction (no convection). Plot the temperature of the egg over time and use the data tooltip in MATLAB to make your conclusion on the time it takes to cook the egg in minutes.arrow_forward
