Test everyone 10: Heat exchange tubes are not included in the tube box volume

Fixed tube sheet heat exchanger: A: Tube side volume = tube box volume 1 + volume in the heat exchange tube bundle + tube box volume 2 B: Tube side volume = tube box volume (larger volume) + volume C in the heat exchange tube bundle: Pipe pass volume = pipe box volume 1 + pipe box volume 2 D: Pipe pass volume = pipe box volume (the one with the larger volume). When using a U-shaped pipe, it includes the volume of the U-tube straight pipe plus the bent pipe. Discuss.
The tube side must be included in the volume inside the heat exchange tube. The volume of the shell side does not need to be deducted from the volume occupied by the heat exchange tube.
I haven't noticed this issue yet. It probably doesn't count.
Does the moderator have a problem with this question? Do you want to ask whether the volume meter in the heat exchange tube is not included in the volume of the tube side?
Moderator, change the shell side volume in the question to the tube side volume. The tube boxes are divided into tube box 1 and tube box 2.
Thanks for the correction. What do you think about this issue:handshake
Volume involves process calculation and classification of containers. For the tube side, it should be the volume of the tube side medium circulation, that is, the internal volume of the tube bundle plus the volume in the tube box. As for the original poster's question, A is the most complete answer. In fact, it is more meaningful to discuss the shell side volume.
To put it bluntly, choose item a. Because the pipe bundle contains multiple pipe holes, it is approximately considered that there is no obstruction to the connection between the two pipe boxes. Choosing the maximum volume will not be a problem for construction safety and strengthening design considerations. It mainly involves supervisory inspection, cycle, and economy.
The tube side is the inside of the heat exchanger tube bundle and the parts it passes through.
