The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 75 kg (165 lb) person of height 1.75 m (5.7 ft) would have a body surface area of approximately 1.90 m2. What is the net amount of heat this person could radiate per second into a room at 19.0 °C (about 66.2 °F) if his skin's surface temperature is 30.0 °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.)
On a cold winter morning you step outside to get into your car and drive to work. Your car's windshield is covered with ice at −15.3°C. If the area of the windshield is 1.40 m2 and it takes 1.97 105 J of heat to melt the ice, how thick was the ice covering the windshield? The latent heat of fusion of ice is 334 kJ/kg, the specific heat of ice is 2092 J/(kg · °C) and its density is 917 kg/m3.
A Thermopane window of area 5 m² is con- structed of two layers of glass, each 4.4 mm thick separated by an air space of 3 mm. If the inside is at 11°C and the outside is at -24°C, what is the heat loss through the window? The thermal conductivity of glass is 0.8 W/m .° C and of air is 0.0234 W/m .° C. Answer in units of kW.
A ceramic container used for melting metals (called a crucible) contains 1.30 kg of a molten metal. The liquid metal cools until it reaches its melting point of 1,749°C. A scientist then measures that 2.99 ✕ 104 J of heat is transferred out of the metal before it completely solidifies. What is the latent heat of fusion of this metal, in J/g? (Be careful with units!)
On a sunny day when the outside temperature is 34.0°C, a car parked in the sun is receiving 812 watts/m2 of incoming solar radiation (Insolation). Because the car radiates heat off of a greater surface area, the car in-turn radiates off heat at a rate of 169 watts/m². If the car is considered a perfect absorber and emitter of radiative energy, what will the equilibrium temperature inside the car be? °C
On a cold winter morning you step outside to get into your car and drive to work. Your car's windshield is covered with ice at −14.3°C. If the area of the windshield is 1.40 m2 and it takes 1.77 105 J of heat to melt the ice, how thick was the ice covering the windshield? The latent heat of fusion of ice is 334 kJ/kg, the specific heat of ice is 2092 J/(kg · °C) and its density is 917 kg/m3 (answer in m).
If the heat is assumed to be generated 0.03 m below the skin, the temperature difference between the skin and the interior of the body would exist if the heat were conducted to the surface is 28 k°. What is the heat rate if the surface area of the body is 1.5m? and the coefficient of the thermal conductivity= 0.2watt/m.k°. 290 watt 310 watt 280 watt 260 watt
When excessive heat is produced within the body, it must be transferred to the skin and dispersed if the temperature at the body interior is to be maintained at the normal value of 37.0 °C. One possible mechanism is conduction through body fat. Suppose that heat travels through 0.03 m of fat in reaching the skin, which has a total surface area of 1.6 m2 and a temperature of 34.5 ° C. How much heat is transferred to the skin in 10 minutes, assuming the conductivity of body fat to be k = 0.20 J/ (s*m*° C)? Q unit
