Piping network heat loss
Piping network heat loss
(OP)
Dear All,
Is it worth it to consider downsizing the piping network to solve heat loss issue?
As we know, smaller surface area should has smaller heat loss

Consider the fact that the ratio of pipe's circumference to crossectional area is 2/r; the same ratio as applied to volumes is why babies lose heat faster than adults.
Additionally, smaller diameter pipe means that maintaining the same mass flow will require higher fluid velocities, which means increased pressures, possibly, as well as potentially increased pipewall erosion problems.

RE: Piping network heat loss
Main point I wanted to make is to be cautious if you are insulating small pipe... insulating can increase the heat loss! Increased surface area can more than make up for increased insulation. Limit is set by dividing k by h. {W/(m °C)} / {W/(m^2 °C)} = m. k/h = critical radius. If you are under the critical radius then you increase heat loss.
