Heat Transfer: Conduction and conductivi-Rate of heat flow
Q: (a) Find the rate of energy flow through a copper block of cross-sectional area 15 cm^2 and length 8.0 cm when a temperature difference of 30 degree C is established across the block. Repeat the calculation assuming the material is (b) a block of stagnant air with these dimensions; (c) a block of wood with these dimensions.
