In designing the heat exchangers single pass (2 tube pass), I put superheated steam 200C - saturated steam 100C to heat Water from 25C to 60C. Steam is put in Shell side and cool water in Tube side. The velocity result in the shell side is quite big. Meanwhile in the tube side, it is in an accepted range for velocity of water in tube side. Is big velocity not acceptable in the shell side? Is there standard for steam velocity in shell side like standard water velocity in tube side (1-2.5 m/s)? 

 
Please look at the excel file. Thank you.

Where is the attachment? what is your intent here, desuperheating steam or heating the water? other than just the velocity of steam on shell side, pay attention to vibrations if any.
