Atomato can be idealized as a sphere with internal heat generation that is due to ripening. consider a tomato with a diameter of 80 mm, density of 840 kg/m", thermal conductivity of 0.5 w/(mk), uniform internal hea generation of 4000 j/(kg*day), and a film coefficient of 7.5 w/(m²k). if the tomato is wrapped in 5 mm of urethane foam, k.026 w/(mk), estimate the steady state temperature at the center of the sphere with a surrounding air temperature of 2°c.
