I. Design of Fins (35 pt). A stripping process produces a hot fluid (80°C) that flows inside copper pipe of 20 cm diameter (the thickness of the pipe wall is negligible). Outside the pipe, there is air flow at ambient temperature (20 °C). In order to recirculate the fluid produced, it is necessary to cool it down. This can be achieved by installing ten circular fins per meter of pipe (see figure below). These fins have a thickness of 0.1...
