The surface temperature of our Sun is about 5800K. Assuming that it acts as a blackbody:
(a) What is the power flux radiated by the Sun, in W/m2?
(b) If the surface area of the Sun is 6.087 x 1012m2, what is the total power emitted in watts?
(c) Because watts are .I/s, how many joules of energy are radiated in one year ( 365 days)? (Note: The Sun is actually a very poor approximation of a blackbody.)

The surface area of an average person (in m2) isgiven by:

A= 7.184E-3(mass0.452)(height0.725)

where mass is in kg (weight in lb times 0.454) and height is incm

a)Assuming that you are an ideal blackbody radiator, compute thenet power that you radiate into a room at a comfortable ambienttemperature of 25C. Net is power radiated minus power absorbed, ofcourse. (Recall that body temperature is 37C).

b)If you were to try to dress in an unheated room at freezingtemperature, recompute the net power that you radiate. This shouldquantify discomfort. Note: this requires very little adjustment ofyour result for part a)

I have more information to a problem I asked about earlier. Icontinue to get an answer of 18 degrees Kelvin which is differentfrom an answer I received earlier. It is my fault since I did notgive the entire question previously.

Here is the question:
A garage (24ftx24ftx10ft) is illuminated by (6) 60W incandescentbulbs. It is estimated that 90% of the energy to an incandescentbulb is dissipated as heat. If the bulbs are on for 3 hours, howmuch would the temperature in the garage increase because of thelightbulbs (assuming no energy losses).
Information Given:

Formula Q=MCpDeltaT
Q is the amount of energy added (joules)
M is the mass of the fluid (kg)
Cp is the heat capacity of the fluid (joules/kg/K)
Delta T is the change in temperature (K or °C)

Number of Lightbulbs: 6
Power From Each Lightbulb (Joules/second): 60
Bulb % Power Loss as Heat: 90%
Amount of Time Bulbs in "On" Position (Hrs): 3
Time Bulbs On (Seconds): 10800
Garage Air Volume (ft3): 5760
Air Density (kg/m³): 1.2
Air Heat Capacity (Joules/kg/K): 1000


Three Hrs of Power from 1 Bulb (watts): ?
Three Hrs of Power All 6 Bulbs (watts): ?
Total Bulb Power Lost as Heat (joules/second): ?
Total Bulb Energy Lost as Heat (joules): ?
Garage Air Volume (m³): ?
Garage Air Mass (kg): ?
Temperature Change (K): ?

A concrete slab is 11.4 cm thick and has an area of 4.3 m2.Electric heating coils are installed under the slab to melt the iceon the surface in the winter months. What minimum power must besupplied to the coils to maintain a temperature difference of17.6°C between the bottom of the slab and its surface? Assume allthe energy lost is through the slab.
