A firewalker runs across a bed of hot coals without sustaining burns. Calculate the heat transferred by conduction into the sole of one foot of a firewalker given that the bottom of the foot is a 3.00-mm-thick callus with a conductivity at the low end of the range for wood and its density is 300 kg/m3. The area of contact is 25.0 cm2 the temperature of the coals is 700 , and the time in contact is 1.00 s. Ignore the evaporative cooling of sweat.
Why is a person able to remove a piece of dry aluminum foil from a hot oven with bare fingers, whereas a burn results if there is moisture on the foil?
If you place 0 ice into 0 water in an insulated container, what will the net result be? Will there be less ice and more liquid water, or more ice and less liquid water, or will the amounts stay the same?
A certain steel railroad rails 13 yd in length and weighs 70.0 lb/yd How much thermal energy is required to increase the length of such a rail by 3.0 mm? .Note: Assume the steel has the same specific heal as iron.
A heater of total radiating surface area of 0.50 m2 is kept at a constant temperature of 100oC. The heater is in a room and keeps the room at a temperature of 25oC. If the emissivity of the heater is 0.8, what is the rate at which the heater supplies heat to the room? σ = 5.67 x 10-8 W/m2K4
The ground temperature a few meters below the surface is fairly constant throughout the year and is near the average value of the air temperature. In areas in which the air temperature drops very low in the winter, the exterior unit of a heat pump designed for heating is sometimes buried underground in order to use the earth as a thermal reservoir. Why is it worthwhile to bury the heat exchanger, even if the underground unit costs more to purchaseand install than one above ground?
The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 75 kgkg (165 lblb) person of height 1.85 mm (6.07 ftft) would have a body surface area of approximately 2.00 m2m2. Part A What is the net amount of heat this person could radiate per second into a room at 17.0 ∘C∘C (about 62.6 ∘F∘F) if his skin's surface temperature is 31.0 ∘C∘C? (At such temperatures, nearly all the heat is infrared radiation, for which the body's emissivity is 1.0, regardless of the amount of pigment.) Express your answer with the appropriate units. HnetHnet = nothingnothing SubmitRequest Answer Part B Normally, 80%% of the energy produced by metabolism goes into heat, while the rest goes into things like pumping blood and repairing cells. Also normally, a person at rest can get rid of this excess heat just through radiation. Use your answer to part A to find this person's basal metabolic rate…
Imagine a person standing naked in a room at 19.1°C. The walls are well insulated, so they also are at 19.1°C. The person’s surface area is 2.20 m2, and his basal metabolic rate is 2167 kcal/day. His emissivity is 0.970. If the person’s skin temperature were 38.2°C (the same as the internal body temperature), at what net rate would heat be lost through radiation? (Ignore losses by conduction and convection.)
An electric kitchen range has a total wall area of 1.40 m2 and is insulated with a layer of fiberglass 4.0 cm thick. The inside surface of the fiberglass has a temperature of 175 degrees C and its outside surface is at 35 degrees C. The fiberglass has a thermal conductivity of 0.040 W/(m*K). What is the heat current through the insulation, assuming it may be treated as a flat slab with an area of 1.40 m2? What electric-power input to the heating element is required to maintain this temperature?
You are asked to design a heating system for a swimming pool that is 2 m deep, 25 m long, and 25 m wide. Your client desires that the heating system be large enough to raise the water temperature from 20 to 30°C in 3 h. The rate of heat loss from the water to the air at the outdoor design conditions is determined to be 960 W/m2, and the heater must also be able to maintain the pool at 30°C at those conditions. Heat losses to the ground are expected to be small and can be disregarded. The heater considered is a natural gas furnace whose efficiency is 80 percent. What heater size (in kW input) would you recommend to your client?
In a one-shell and two-tube heat exchanger, cold water with inlet temperature of 20°C is heated by hot water supplied at the inlet at 80°C. The cold and hot water flow rates are 5000 kg/h and 10,000 kg/h, respectively. If the shelland- tube heat exchanger has a UAs value of 11,600 W/K, determine the cold water and hot water outlet temperatures. Assume cpc = 4178 J/kg·K and cph = 4188 J/kg·K.
A concrete slab is 12.0 cm thick and has an area of 5.00 m2. Electric heating coils are installed under the slab to melt the ice on the surface in the winter months. What minimum power must be supplied to the coils to maintain atemperature difference of 20.0°C between the bottom of the slab and its surface? Assume all the energy transferred is through the slab.
