See Answer. Question: The rate of conduction heat transfer through a plane wall of dimensions H, W, and L, thermal conductivity k, and temperatures Ti and T2 on the faces can be determined as W T H L (T2 - T6) q = - LK HW q = - Hk (T2 – T1) L (T2 - T6) = - HWK- L q= HWk (T2 - T6). Convection is transfer of thermal energy in a fluid by O a ...

True or false: In heat transfer, the conduction shape factor can be used when the medium between the two surfaces is a fluid and the heat transfer is by natural convection but not when heat transfer is by forced convection. There are 3 steps to solve this one. Solution. Answered by.
