Pipe heat loss

Webb13 nov. 2015 · The heat-transfer equations should, after all, lead to stable results. If the temperature at point x is estimated to be a bit higher than the true value, then the temperature drop over the interval between x and x + Δ x would increase as well. Increasing Δ x by a factor of 100 naturally cuts the computation by a factor of 100. Preamble WebbYour calculations are very simplified. The general procedure for the convection part for this type of pipe through room problem is: 1 - Calc. Coefficient of thermal expansion 2 - calc. Rayleigh number 3 - calc. Nusselt number 4 - calc. convective heat transfer coefficient 5 - calc. convective heat transfer.
