ABSTRACT
This report gives an introduction of the cooling tower and its operation. The theoretical
underpinning of the cooling tower and its construction is discussed. The paper proceeds to
discuss the use of the PA Hilton Bench-top Cooling Tower and how it operates while connected
to an inclined manometer that measures the pressure. The mass flow rate is determined at the
onset and heat exchange rate. From the experiment, different temperatures are recorded form the
dry bulb and wet bulb temperatures at the column section of the hygrometer. The reading and
measurements are recorded in different tables in the cooling load as illustrated in the appendix A,
B, and C. Holding all other factors constant, the evaporation rate is linear as the water being
passed through the cooling tower passes through the filler but it stagnates when the air flow rate
attains 100 percent humidity.

INTRODUCTION
A cooling tower is used in cooling liquids stored inside it. The tower is a collection of
equipment which is used to obtain the primary cooling effect from the evaporation of water once
the system is brought into direct contact with air. These towers either implement natural draft or
