Question

A hot dog with a diameter of roughly 2 cm and initial temperature 20°C is dropped into pool of 95°C water. The heat transfer coefficient may be assumed to be constant and equal to 200 W/m²⋅K. The meat thermal conductivity and thermal diffusivity are approximately 0.4 W/m⋅K and 0.0014 cm²/s.
a. How long do we have to wait until the center of the hot dog warms up to 65°C
b. Estimate the hot dog surface temperature at the time calculated in part (a)

Answer 1

using heisler charts and given data we can calculate time and temperture
