I’d like to ask the experts! Is this selection for the shell-and-tube heat exchanger correct?

Also, is the shell side of the heat exchanger 11 stages in diameter 200? I calculated based on the conditions shown in the diagram and the heat resistance due to dirt; it requires 200 square meters. Based on my experience, for ordinary industrial brine with dirt accumulation, a heat exchange area of around 30 square meters is required‘ ； ； For 45t/h, pipes with DN100 are more suitable
This is the information provided by the customer, and I think it’s not sufficient either, so I’m trying to verify it. Thank you for your help, sir: handshake
