A large slab of steel 0.1 m thick has in it a 0.1 m-diam hole, with axis normal to the surface. Considering the sides of the hole to be black, specify the rate of radiative heat loss from the hole in W and Btu/hr. The plate is at 811 K, the surroundings are at 300 K.GIVENA large slab of steel with a hole whose axis is normal to the surfaceSlab thickness (S) = 0.1 mHole diameter (D) = 0.1 mPlate temperature (T1) = 811 KTemperature of surrounding (T??) = 300 KASSUMPTIONSThe sides of the hole areblack
