Our Sun has a peak emission wavelength of about 500 nm and a
radius of about 700,000 km. Your dark-adapted eye has a pupil
diameter of about 7 mm and can detect light intensity down to
about 1.5 x 10-11 W/m². Assume the emissivity of the Sun is equal
to 1.
First, given these numbers, what is the surface temperature of the
Sun in Kelvin to 3 significant digits?
5,796
The amount of radiant energy emitted by a
surface is given by
q = ɛ0 AT+
where
q represents the rate of thermal energy
(per unit time) emitted by the surface in watts;
e = the emissivity of the surface 0<ɛ<1
and is unitless
o = Stefan-Boltzman constant
(o = 5.67×10% )
A represents the area of the surface in m²
Ty = surface temperature of the object
expressed in kelvin
What are the appropriate units for o if the
equation is to be homogeneous in units?
An incandescent light bulb with a surface area of 0.0108 m2 and an emissivity of
0.87 has a surface temperature of 171.3°C. If the temperature of the
surroundings are 21.2°C, what is the net rate of radiation heat transfer between
the bulb and the surroundings? [round your final answer to one decimal place]?
