A thick aluminum block initially at 26.5°C is subjected to constant heat flux of 4000 W/m2 by an electric resistance heater whose top surface is insulated. Determine how much the surface temperature of the block will rise after 2112 seconds. Consider the diffusivity of pure aluminum to be 9.71 × 10−5 m2/s and conductivity of pure aluminum to be 237 W/m·k.
Determine how much the surface temperature of the block will rise after 30 minutes.
