Cooling towers are of two types: Natural draft and Mechanical draft.
Natural draft cooling towers use natural air flow to cool water
Mechanical draft cooling towers use fans to force air through the tower
Natural draft towers are larger and more expensive than mechanical draft towers
Mechanical draft towers are more common in industrial applications
Examples of cooling towers include crossflow, counterflow, and hyperbolic
Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.
Transformers work on the principle of electromagnetic induction
They consist of two coils, primary and secondary, wound around a magnetic core
Types of transformers include step-up, step-down, isolation, autotransformer, and instrument transformer
Step-up transformers increase voltage while step-down tran...
