Tube diameter : Using a small tube diameter makes the heat exchanger both economical and compact. However it is more likely for the heat exchanger to foul up faster and the small size makes mechanical cleaning of the fouling difficult. To prevail over the fouling and cleaning problems larger tube diameters can be used. Thus to determine the tube diameter the available space cost and the fouling nature of the fluids must be considered.

• Tube thickness : The thickness fo the wall of the tubes is usually determined to ensure
• Ther is enough room for corrosion
• That flow induced vibration has resistance
• Axial strength
• Ability to easily stock spare parts cost sometimes the wall thickness is determined by the maximum pressure differential across the wall.
