Cooling tower water Assessment

What is the Cycle of Concentration (COC)?

• The ratio between makeup and blowdown.

• The ratio between heat and cooling.

• The ratio between fluid and deposits.

• The ratio between scaling and fouling.

What is fouling in the context of heat exchangers?

• The formation of hard deposits on surfaces.

• A very undesirable phenomenon in the world of heat transfer and heat exchangers.

• The ratio between makeup and blowdown.

• The process of cooling fluids.

What can cause fouling in heat exchangers?

• Clean water.

• Pure air.

• Dirt, oil, grease, and chemical or organic deposits.

• High temperatures.

What is scaling in the context of heat exchangers?

• The process of cooling fluids.

• The formation of hard deposits on surfaces.

• The ratio between makeup and blowdown.

• The process of heating fluids.

Where does metal loss occur in the corrosion process?

• At the cathode

• At the anode

• In the electrolyte

• In the circuit

What does the Holding Time Index (HTI) determine?

• The effectiveness of species in water

• The rate of metal loss

• The speed of oxidation

• The electrical conductivity

What is the relationship between HTI and the effectiveness of chemicals?

• Longer HTI means higher effectiveness

• Shorter HTI means lower effectiveness

• Longer HTI means lower effectiveness

• HTI does not affect effectiveness

What is the most common cooling system design?

• Closed Recirculating Systems

• Open Recirculating Systems

• Single-Pass Systems

• Dry Cooling Systems

How is water reused in open recirculating systems?

• By disposing it after one use

• By recycling it across a cooling tower

• By using it in a closed loop

• By evaporating it completely

How is the tower water cooled for reuse in open recirculating systems?

• By freezing

• By condensation

• By evaporation

• By heating
