1. Objective
1) To know about principle of double pipe heat exchanger.
2) To measure the overall heat transfer coefficient by heat transfer equation.
3) To calculate logarithmic mean temperature difference and overall heat transfer coefficient with equipment, then discuss about efficiency of parallel flow and counter flow.
<중 략>
1. Discussion
1) Discuss the reason of different heat transfer coefficient for co-current flow and counter-current flow.
Figure 1. Co-current
Figure 2. Counter current
As we can see, at the co-current flow, the temperature difference of hot and cold water is decreasing as time goes. On the contrary, at the counter-current flow, the temperature difference of hot and cold water is slightly increasing as time goes. So, the logarithmic mean temperature at co-current flow and counter current flow will not be same, where the logarithmic mean temperature is following.
