Consider a person floating in space. Calculate the blackbody luminosity (energy radiated per second) of the person and also the rate of energy absorbed from CMB photons (T 2.73 K). At what rate does the person cool off, i.e. dT/dt? For simplicity, assume a spherical person with 1 m diameter, temperature of 310 K, and who absorbs and radiates as a perfect blackbody. To calculate temperature change, assume that this person has the same heat capacity as water, C 4200.Jkg...
The rate of heat transfer by emitted radiation is determined by the Stefan-Boltzmann law of radiation = ceAT4 t where a 5.67x108 J/(s m2. K4) is the Stefan-Boltzmann constant, A is the surface area of the object, and T is its absolute temperature in kelvin. The symbol e stands for the emissivity of the object, which is a measure of how well it radiates. An ideal jet-black (or black body) radiator has e 1, whereas a perfect reflector has e...
6. Usually radiation heat fluxes are distinguished. Answer their names in the following questions, assuming they are defined over all wavelengths and in all directions Reflection, E + Grel Grt Emission, G Opaque medium 1) What is the rate at which radiation is incident upon a surface per unit area, G (W/m2)? 2) What is the rate at which radiation leaves a surface due to emission and reflection per unit area of the surface, J(W/m2)? 3) Calculate the net rate...

1. Heat transfer analysis of a special-purpose panel is to be performed. The temperatures at the inner and outer surfaces of the panel measure 30°C and 22°C, respectively. The dimension of the panel is 2.9 m wide, 1.3 m high and 0.40 cm thick. Its thermal conductivity is 0.13 W/m·°C. Heat is lost from the outer surface by convection and radiation. The convective heat transfer coefficient is 23 W/m2 ·°C and an ambient temperature measures 13°C. Determine (a) the fraction...
pe the earth at a rate of around 30 watts per cubic kilometer. (A watt is a rate of heat production.) The heat then flows to the earth's surface where it is lost to space. Let F(x,y, z) denote the rate of flow of heat measured in watts per square kilometer. By definition, the flux of F across a surface is the quantity of heat flowing through the surface per unit of time. (a) Suppose that the actual heat generation...
A 1.88 -m ( 6 ft 2 in. ) man has a mass of 81 kg, a body surface area of 1.8 m 2 , and a skin temperature of 35.7 ∘ C. Normally, 80 % of the food calories he consumes go to heat; the rest goes to mechanical energy. His emissivity e is 1 because his body radiates almost entirely nonvisible infrared energy, which is not affected by skin pigment. (Careful! His body at 35.7 ∘ C radiates...
