Figure shows a cooling tower operating at steady state. Warm water from an air-conditioning unit enters at 49 °C with a mass flow rate of 0.5 kg/s. Dry air enters the tower at 21° C, 1 atm with a volumetric flow rate of 1.41 m/s. Because of evaporation within the tower, humid air exits at the top of the towver with a mass flow rate of 1.64 kg/s. Cooled liquid water is collected at the bottom of the tower for return to the air-conditioning unit together with makeup water. Determine the mass flow rate of the makeup water, in kg/s.

Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.
