The optimum diameter of a pump depends on various factors such as flow rate, head, viscosity, and efficiency.

• The diameter should be selected based on the required flow rate and head of the system.

• Higher viscosity fluids require larger diameter pumps to reduce frictional losses.

• Efficiency of the pump increases with larger diameter impellers.

• The diameter should also be selected based on the available space and cost const...read more

Stream balance inside distillation column is crucial for efficient separation of components.

• Stream balance refers to the equal distribution of feed and product streams across the column.

• Imbalance can lead to poor separation efficiency, flooding, or tray damage.

• Factors affecting stream balance include tray design, liquid and vapor flow rates, and column diameter.

• Techniques such as tray hydraulics and computational fluid...read more
