Consider we have a 2-4Shell and Tube Heat Exchanger, with the inner tube of Outer diameter 20mm (thickness 2mm) and shell of inner diameter 100mm. We have two fluids A & B, both of density 990 Kg/m3, we desire to have their flow rates as 15 m/s and 21 m/s respectively, friction factor of 0.00096 and 4 tube of length 0.4 m and 2shell passes. If the maximum pressure drop allowed on shell side is 10atm, is the setup suitable for industrial use?

• A. No, since pressure drop is less than specified
• B. Yes, since pressure drop is less than specified
• C. No, since pressure drop is more than specified
• D. Yes, since pressure drop is more than specified
