Question

Which of the following devices in not based on Pascal&#8217;s law.a)syringeb)hydraulic brakesc)hydraulic liftd)AtomiserCorrect answer is option 'D'. Can you explain this answer?

Answer

In Atomiser Pascal's law is interpreted .... Because ... In Atomiser ... Change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all point in the fluid ...

Answer

All atomizer work on the principle of air flow and suction i.e. on Bernoulli's principle and not on Pascal's law. thus, op D.

Answer

The correct answer is option 'D', Atomizer.

Explanation:
Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase in pressure throughout the entire fluid. This principle is the basis for many hydraulic devices that operate using fluid pressure.

Devices based on Pascal's law:

- Syringe: A syringe is a medical device that is used to inject or withdraw fluids from the body. It consists of a cylindrical barrel, a plunger, and a needle. By pushing or pulling the plunger, the fluid inside the syringe can be injected or withdrawn. The pressure applied to the plunger is transmitted equally throughout the fluid, allowing for precise control and application of force.

- Hydraulic brakes: Hydraulic brakes are commonly used in vehicles to provide braking power. They operate on the principle of Pascal's law. When the brake pedal is pressed, it applies force to a small piston in the master cylinder. This force is transmitted through a fluid-filled line to the brake calipers or wheel cylinders located at each wheel. The pressure is distributed equally to all the brake calipers or wheel cylinders, causing the brake pads or shoes to press against the brake discs or drums, generating friction and slowing down the vehicle.

- Hydraulic lift: A hydraulic lift is a device used to raise heavy loads by applying Pascal's law. It consists of a fluid-filled cylinder with a piston and a lifting platform. When force is applied to the small piston, it creates pressure in the fluid, which is transmitted equally to the larger piston. This pressure causes the larger piston to rise, lifting the platform and any load placed on it.

Device not based on Pascal's law:

- Atomizer: An atomizer is a device used to disperse liquid into a fine mist or spray. It is commonly used in perfume bottles, air fresheners, and spray bottles. Atomizers operate on the principle of Bernoulli's principle and fluid flow dynamics, not Pascal's law. The liquid is forced through a small nozzle or orifice, creating a high-velocity stream that breaks up into droplets due to the surrounding air pressure and flow dynamics.
