For the shell side and tube side of a heat exchanger, as well as the sizes of the inlet and outlet ports, when the user does not provide this information and only gives the flow rate, how should the diameter be determined? ? ? Based on what? ? What does size affect? ? ? For the soda water heat exchanger: steam flow rate is 3221 Kg/h, density is 926 Kg/m³; the flow velocity is taken as 15 m/s. The volume is calculated as flow velocity multiplied by 3.1415926 times the square of the pipe radius. The diameter DN calculated in this way is 10, but it seems incorrect. Could you tell me what’s wrong? ? ? ?
It’s very simple: just choose the flow rate yourself; if you’re using circulating water, use 1. 5 m/s; after calculating the pipe diameter, round it off.
