Heat transfer coefficients of stainless steel bellows tubes and copper threaded tubes

2009-03-13View Original

Thread Content

I have now calculated 1 gas-water heat exchanger and 1 water-water heat exchanger. The heat exchange tubes in the steam-water heat exchanger are made of stainless steel corrugated tubes, while those in the water-water heat exchanger are made of copper threaded tubes. However, after calculating the required heat exchange area, the result differed significantly from what my colleagues calculated. Upon closer inspection, it’s all due to the heat transfer coefficient. Please ask the teacher to help solve this.
