WebSteady state heat transfer through pipes is in the normal direction to the wall surface (no significant heat transfer occurs in other directions). Therefore, the heat transfer can be h, T∞ T1 k2 k1 A2 A1 Insulation L1 T1 T∞ Q• Q• Q1 • Q2 • R1 R2 k3 A3 L3 R3 Rconv In the study of heat transfer, fins are surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction, convection, or radiation of an object determines the amount of heat it transfers. Increasing the temperature gradient between the object and the environment, increasing the convection heat transf…
