Cooling Tower

Cooling water is used to

• Cool the space or room

• Cool the hot water coming from the condenser

• Freeze the water

• Increase the pressure of water

In the cooling tower, water is cooled by the process of ___________.

• Condensation

• Fusion

• Evaporation

• Sublimation

In crossflow, distribution of hot water is under pressure through an enclosed tubing and outlet with spray nozzle to the cooling tower fill.

• True

• False

The purpose of louver is _______

• To change the direction of air inlet flow in the uniform manner

• To prevent the water droplets splashing out of the tower

• Both of the above

• None of the above

Purpose of drift eliminator is

• To reduce the entrainment of water droplets in air stream

• To prevent the water droplets splashing out of the tower

• To provide the required surface area for heat transfer

• All of these

The purpose of cooling tower basin is

• To serve as receptacle for cooled water

• To provide the storage capacity during makeup water failure

• To remove stagnant water and prevent the growth of bacteria by keeping a continuous water flow through it

• All of these

The purpose of fill is

• To prevent the water droplets splashing out of the tower

• To provide the required surface area for heat transfer between air and the water

• To reduce the entrainment of water droplets in air

• To change the direction of air inlet flow in the uniform manner

Cooling towers operate on the principle of __________.

• Henry's Law

• Stefan-Boltzmann Law

• Evaporative cooling

• All of these

In counter flow induced draft cooling towers water and air both enter the top and exist at the top of the cooling tower.

• True

• False

In a forced draft cooling tower, the fan is fixed at the

• top of the cooling tower

• middle of the cooling tower

• bottom of the cooling water

• any location of the cooling tower
