How to determine the number of tubes in the tube side of a shell and tube heat exchanger
It is determined through trial calculations using a heat exchanger calculation program. For estimation, first calculate the total area and select a heat exchanger; this determines the number of main tubes. Based on the flow rate of the fluid in the tube side and the typical flow velocity of such fluids, the number of tubes per tube side can be calculated. The required number of tube sides is then equal to the total number of main tubes divided by the number of tubes per tube side calculated above. Considering the issue of partitioning, the number of pipe stages is generally 1, 2, 4, 8, etc. If the data does not match this, select again until a suitable value is found.
With careful consideration, the number of tube passes can be calculated based on the number and type of partitions at both ends.
Based on the flow velocity calculation, the fluid in the tube side is adjusted to meet the standard values. The second floor is correct.
