Seeking help: How to account for the hydrostatic pressure of the liquid column in vertical heat exchangers?
Thread Content
Question: For a vertical heat exchanger with a design pressure of 4.3 MPa for both the tube side and the shell side, tube length of 3000, and an overall height of approximately 4506, is it necessary to take into account the hydrostatic pressure of the liquid column? Is it necessary to consider the static pressure of the liquid column in the shell side and the tube side separately?
If one wants to determine whether the static pressure of the liquid column exceeds 5% of the design pressure, how should the tube side and shell side be considered?

0.1 MPa is approximately equivalent to 10 meters of water column; if your equipment is based on a height of 5 meters, the pressure would be only 0.05 MPa. Calculate the design pressures for the tube side and shell side to determine whether the static pressure due to the water column needs to be taken into account: victory:
The hydrostatic pressure of the liquid column is too low compared to the design pressure, so it is unnecessary to take it into consideration.
I’ve learned it~~~ Thank you so much!~~~
Only the hydrostatic pressure of the liquid column is added during the horizontal hydraulic test. It is generally not considered under operating conditions.
