Use HTRi for heat exchanger design

Why is the flow rate in the basic data provided by the manufacturer multiplied by 1.1, and why does the value entered during design also need to be multiplied by 1.1?
Extreme assumptions should be made, increasing the margin to 10%
Generally, there is a margin of 10% to 20%; 10% corresponds to multiplying by 1.1.
Do the data used in the design need to be multiplied by 1.1?
I believe that it is necessary during the design phase to generate process calculation data, so as to accurately determine whether the equipment parameters meet the process requirements.
Nonsense. Multiplying by 1.1 corresponds to the operating margin required in standard process packages, which is 60%-110% of the normal level; multiplying by 1.1 represents the maximum processing capacity of the facility. Of course, manufacturers provide figures based on the maximum processing capacity, and operating margin must be taken into account during design.
