Chapter 13, Problem 01 The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 280 J/s. The energy is transferred a distance of 2.1 × 10-3 m through a body whose surface area is 1.8 m2. Assuming that the thermal conductivity is that of body fat, determine the temperature difference between the capillaries and the surface of the skin.

(a) What is the rate of heat conduction (in W) through the 2.00 cm thick fur of a large animal having a 1.30 m2 surface area? Assume that the animal's skin temperature is 30.0°C, that the air temperature is −6.50°C, and that fur has the same thermal conductivity as air. (Assume the thermal conductivity of air is 0.023 J/(s · m · °C).) W (b) What food intake (in kcal) will the animal need in one day to replace this...

PLEASE ANSWER a,b,c
Heat Conduction Heat conduction occurs through any material, represented here by a rectangular bar, whether window glass or walrus blubber. The temperature of the material is T2 on the left and T1 on the right, where T2 is greater than T1. The rate of heat transfer by conduction is directly proportional to the surface area A, the temperature difference T2 - T1, and the substance's conductivity k. The rate of heat transfer is inversely proportional to the...

Given human body core temperature=37C, skin surface temperature=33C, surface area of body=1.5m^2, and average thickness=1.0cm. Thermal conductivity is 0.2J/(s*m*degree). If one takes into account heat conduction through the skin as the only mechanism for energy dissipation from the body how long would it take to dissipate all the energy contained in a food consisting of 140 Calories?

(a) Calculate the rate of heat conduction (in W) through a double-paned window that has a 5.00 m2 area and is made of two panes of 0.700 cm thick glass separated by a 1.00 cm air gap. The inside surface temperature is 17.0°C, while that on the outside is −20.0°C. (Hint: There are identical temperature drops across the two glass panes. First find these and then the temperature drop across the air gap. This problem ignores the increased heat transfer...
