Question
B:Consider a cylindrical pipe of outer radius r whose outer surface temperature T₁ is
maintained constant. The pipe is now insulated with a material whose thermal
conductivity is k and outer radius of the insulation is 12. Heat is lost from the pipe to
the surrounding medium at temperature Too, with a convection heat transfer
coefficient (h). Dreive the critical insulation thickness and explaine the effect of re on
the rate of heat transfer.
