The temperature drop issue in pipes without insulation
Thread Content
The temperature inside the reactor is 170 degrees. The stainless steel pipes have no insulation layer; they have a diameter of 160 mm, a thickness of 3 mm, and a length of 40 meters. The outdoor temperature is 31.5 degrees, with a wind speed of 4 m/s. How can the temperature of the water vapor at the pipe outlet be calculated? Is there still 100 degrees? It’s not even close :'( Help, please! :$
First, calculate the heat dissipation amount, and then determine the outlet temperature based on the steam flow rate and temperature.
Bro, can you explain it to Xiaobai more clearly?:$ It would be best to come up with some formula or something {:1_90:}
First of all, according to the regulations, areas that can be touched by people and where the temperature exceeds 60 degrees must be protected against burns. You need to know the heat transfer coefficient of the steel pipe, so go and look it up
