- 2. 3. HEAT TRANSFER FROM FINNED SURFACES
At the fin tip we have several possibilities, including specified temperature, negligible heat loss (idealized as an insulated tip), convection, and combined convection and radiation as shown in figure 2–21 zero That is, shown in figure 2–22

Kinetic and potential energy changes through the compressor are negligible The nitrogen can be modeled as an ideal gas with a specific heat ratio of 1 391 and a specific heat at constant pressure of 1 056 kJ (kg K) Determine the minimum theoretical power input required to operate the compressor and the corresponding exit temperature

An important concern in the study of heat transfer is to determine the steady-state temperature distribution of a thin plate when the temperature around the boundary is known Assume the plate shown in the figure represents a cross section of a metal beam, with negligible heat flow in the direction perpendicular to the plate
