Temperature drop in underground yellow-jacket pipeline transportation
Thread Content
Dear experts, I am in urgent need of a theoretical calculation formula or empirical data: for hot water transported through underground yellow-jacketed pipes at a temperature of 70–90 degrees Celsius, what is the temperature drop over a distance of 1 kilometer for DN200 pipes? ? Waiting online... Thank you
It depends on the specific flow rate. If the pipeline is buried deep, under normal conditions, the temperature drop per kilometer should not exceed 0.1℃
