The radiative heat loss from an ideal object is well approximated by Stefan-Boltzmann law: j=T4 where j is the thermal energy lost in W/m2,T is the absolute temperature, and =5.67108W/m2/K4 is Stefan 's constant. From our temperature data in smoothtemp.txt, find j at every point on the plate. Recall that the plate is 20cm by 10cm : find the total heat energy lost by radiation by integrating j across this entire area. Note: Be careful with unit conversions.
