Basic Principle of Hot Wire Anemometer
When an electrically heated wire is placed in a flowing gas stream, heat is transferred from the wire to the gas, and hence the temperature of the wire reduces, and due to this, the resistance of the wire also changes. This change in opposition of the wire becomes a measure of flow rate.
∴ A hot wire anemometer is used to measure the velocity of the fluid.

Measuring Velocity with Hot Wire Anemometer
The hot wire anemometer is an instrument used to measure the velocity of a fluid. It is based on the principle of convective heat transfer, where a heated wire is exposed to a fluid flow and the cooling effect of the fluid is used to calculate the velocity of the fluid.
Working Principle of Hot Wire Anemometer
The hot wire anemometer works by heating a thin wire to a constant temperature and exposing it to a fluid flow. As the fluid flows past the wire, it cools the wire, and the cooling effect is measured to calculate the velocity of the fluid. The velocity of the fluid is directly proportional to the cooling effect on the wire. The anemometer has a control unit that maintains a constant temperature of the wire, and the cooling effect is measured using a Wheatstone bridge circuit.
Applications of Hot Wire Anemometer
Hot wire anemometers are widely used in fluid mechanics research, aerodynamics, and HVAC systems. They are used to measure the velocity of gases and liquids in pipes, ducts, wind tunnels, and other flow channels. They are also used to measure the turbulence and flow characteristics of fluids.
Conclusion
The hot wire anemometer is a useful instrument for measuring the velocity of fluids. Its principle of operation is based on convective heat transfer, and it is widely used in fluid mechanics research, aerodynamics, and HVAC systems.
