Increasing reflux ratio reduces condenser duty.
Higher reflux ratio means more liquid is returned to the column.
This increases the liquid flow rate in the column.
As a result, less vapor needs to be condensed in the condenser.
Reduced condenser duty leads to lower energy consumption.
Example: If the reflux ratio is doubled, the condenser duty may be halved.
Heat is transferred in a cooling tower through a combination of evaporation, convection, and radiation.
Evaporation: Water is sprayed into the cooling tower, and as it evaporates, it absorbs heat from the surrounding air.
Convection: The warm water from industrial processes is circulated through the cooling tower, and as it comes into contact with the air, heat is transferred through convection.
Radiation: Heat is al...
Water cannot be used instead of air cooled condensers due to several reasons.
Water is a poor conductor of heat compared to air, resulting in less efficient heat transfer.
Using water as a coolant requires a constant supply of water, which may not be feasible in all locations.
Water cooling systems are more complex and expensive to install and maintain compared to air cooling systems.
Water cooling systems pose a high...
The wet bulb temperature should be more in an air conditioned room than in ambient temperature.
The wet bulb temperature is a measure of the lowest temperature that can be achieved by evaporative cooling.
In an air conditioned room, the air is typically drier and the evaporation rate is higher, leading to a lower wet bulb temperature.
In ambient temperature, the air is usually more humid, resulting in a higher wet bu...

The laws of motion describe the behavior of objects in motion.
The first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force.
The second law states that the force acting on an object is equal to its mass times its acceleration.
The third law states that for every action, there is an equal and opposite reaction.
