Approach of a cooling tower is defined as the:
- Difference of dry bulb temperature of surrounding air and temperature of water leaving the cooling tower
- Difference of temperature of water leaving the cooling tower and wet bulb temperature of surrounding air
- Difference of temperature of water leaving the cooling tower and temperature of water entering the cooling tower
- None of the above
Range of a cooling tower is defined as:
- Difference of dry bulb temperature of surrounding air and temperature of water leaving the cooling tower
- Difference of temperature of water leaving the cooling tower and wet bulb temperature of surrounding air
- Difference of temperature of water leaving the cooling tower and temperature of water entering the cooling tower.
- None of the above
Efficiency of a cooling tower is the ratio of:
- Range to difference of temperature of water entering the cooling tower and temperature of water leaving the cooling tower
- Approach to difference of temperature of water entering the cooling tower and temperature of water leaving the cooling tower
- Range to difference of temperature of water entering the cooling tower and wet bulb temperature of air
- None of the above
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 tower
- Any location of the cooling tower
The purpose of a cooling tower is to:
- Cool the air coming from condenser
- Cool the hot water coming from condenser
- Cool the air coming from condenser through the water
- None of the above
