A hole of radius `r_(1)` is made centrally in a uniform circular disc of thickness d and radius `r_(2)` . The inner surface (a cylinder of length d and radius `r_(1)` is maintained at a temperature `theta_(1)` and the oouter surface (a cylinder of length d and radius `r_(2)` . The is maintianed at a temperature `theta_(2)(theta_(1)gttheta_(2))` .The thermal conductivity of the material of the dics is K. Calculate the heat flowing per unit time through the disc.
