WebThe heat transfer area for a (two-stream) heat exchanger is calculated using a single variable for temperature difference. However, in a heat exchanger there is a range of temperature differences between the hot and the cold stream, over the device surface. To overcome this, a single temperature difference is used to represent the heat exchanger. WebThe surface area ( A) for transferring heat through the pipe (neglecting the pipe ends) is directly proportional to the radius ( r) of the pipe and the length ( L) of the pipe. A = 2πrL As the radius increases from the inner wall to the outer wall, the heat transfer area increases.
