Suppose you walk into a sauna that has an ambient temperature of 50.0 ∘C.

(a) Calculate the rate of heat transfer to you by radiation in watts, given your skin temperature is 37.0 ∘C, the emissivity of skin is 0.98, and the surface area of your body is 1.4 m2.

(b) If all other forms of heat transfer are balanced (the net heat transfer is zero), how much will your body temperature increase if your mass is 70 kg, and sit inside the sauna for 1 h?

A wood fire has a temperature of 600◦C. A person with a total surface area of 1.6 m2 and at a temperature of 34◦C stands next to the fire. If the emissivity is 0.95, determine the rate of radiative heat transfer, in kW. Assume that only one-half of the total person surface area is exposed to the fire.

It’s a hot, 100°F (38°C), summer day and you are going for a picnic. To keep your food and drinks cold, you bring a white Styrofoam cooler packed with ice and put it in the shade. Assuming there is enough ice in the cooler that the inside temperature remains at 0°C, will your cooler receive more heat from radiation or conduction? The cooler is made out of 2 cm thick layer of Styrofoam with a thermal conductivity of 0.010 J/(s...

Consider a person who is trying to keep cool on a hot summer day by turning a fan on and exposing his entire body to air flow. The air temperature is 40°C and the fan is blowing air at a velocity of 2 m/s. If the person is doing light work and generating sensible heat at a rate of 300 kJ/h, determine the average temperature of the outer surface (skin or clothing) of the person. The average human body can...

The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 66 kg (146 lb) person of height 1.83 m (6.0 ft) would have a body surface area of approximately 1.9 m2. What is the net amount of heat this person could radiate per second into a room at 18.0 ∘C (about 64.4 ∘F) if his skin's surface temperature is 31.0 ∘C? (At such temperatures, nearly all the heat...

4.1A clothed or unclothed person feels comfortable when the skin temperature is about 33oC. Consider an average man wearing summer clothes whose thermal resistance is 0.109 m2 ? oC/W. The man feels very comfortable while standing in a room maintained at 20oC. If this man were to stand in that room unclothed, determine the temperature at which the room must be maintained for him to feel thermally comfortable. Assume the latent heat loss from the person to remain the same....

Suppose you are sitting, naked, on a steel bench with a temperature of 10°C. The only thing insulating the core of your body (temperature 37°C) is a layer of skin (the epidermis and dermis together are about 4 mm thick) and fat (varies from individual to individual, but a typical thickness on the buttocks and the back of the thighs might be 1.0 cm.) Estimate the rate of heat loss by conduction under this circumstance. I estimated the area of...
