Correct Answer - Option 2 : Venturimeter
The correct answer is option 2
The Venturimeter works on the ‘Bernoulli's theorem’.
-
Venturimeter - It is a device based on Bernoulli's theorem with the help of which the rate of flow of fluid in a tube is determined.
-
Submarine - It also works on the ‘law of flotation’ and ‘the principle of Archimedes’, which can be used to run the surface of water or underwater.
-
Hydraulic Press – It is a device based on Pascal’s law. Which depends on the following properties of the fluid – Pressure has a negligible effect on the volume of the fluid.
- By applying force or pressure on any part of the fluid, it can be applied to any part of the fluid.
-
Hydrometer - It is a device based on Archimedes's theorem From this, the specific density of the liquids is extracted and their purity is tested.
