The expected distribution for heating and cooling are sketched in Figure 18.12. For heating (), the heat flow from the pipe wall in a length is
Webtemperature is referred to as the cold water temperature due to the fact that it is cooler than water entering the tower. For evaporative processes, the difference between the cold water temperature and entering wet bulb temperatures is the approach. However, there is a lot more to understand about approach than simply the WebIn this paper, a two-step method is proposed to optimize the layout of the conventional serpentine film heater thus to improve the temperature uniformity. The optimization is made on transverse direc
