Final answer:
The exact equation for thermal resistance due to convection through a cylindrical wall is not given, but the heat transfer by convection can be calculated using Q = mcΔT, and other related formulas for conduction and radiation depending on the circumstances.
Step-by-step explanation:
The equation for thermal resistance due to convection through a cylindrical wall is not provided directly, but it can be analyzed using principles of heat transfer. For conduction through a material, the formula Q/t = kA(T₂ - T₁)/d is used, where Q/t is the rate of heat transfer, k is the thermal conductivity, A is the surface area, d is the thickness, and (T₂ - T₁) is the temperature difference across the slab. For convection, the rate of heat transfer by convection can be calculated using Q = mcΔT when the amount of matter ('m' for mass) moved is known, along with its specific heat capacity ('c') and the temperature change (ΔT). If a phase change occurs during convection, the equations Q = mLf or Q = mLv should be used to find the heat transfer associated with the phase change, whereas, for radiation, the net heat transfer rate is given by Q_net = σA(T^4 − T_o^4).
