Hot wire anemometer is used to measure A. discharge B. velocity of gas C. pressure intensity of gas D. pressure intensity of liquid

discharge
velocity of gas
pressure intensity of gas
pressure intensity of liquid

A hot wire anemometer is a device used to measure the velocity of a fluid. It works by passing an electric current through a thin wire that is heated by the current. The heat from the wire causes the air around it to move, and the speed of the air is proportional to the amount of current that is flowing through the wire. The hot wire anemometer can be used to measure the velocity of air, water, or other fluids.

The other options are incorrect because they are not measurements that can be made with a hot wire anemometer. Discharge is the amount of fluid that flows through a pipe or other opening in a given amount of time. Pressure intensity is the force per unit area that is exerted by a fluid.
