What are the applications of Archimedes Principle Class 9?
Applications of Archimedes’ Principle: It is used in designing ships and submarines. It is used in determining relative density of substances. Hydrometers used to determine the density of liquids, work on this principle. Lactometers used to determine purity of milk, are also based on this principle.
What are some applications of Archimedes Pascal’s and Bernoulli’s principles?
The concepts of Pascal’s law, Archimedes’ principle and Bernoulli’s principle are important in engineering and technology applications such as aerodynamics and hydrodynamics, hydraulics, floating vessels, submersibles, airplanes, automobiles, aerospace guidance and control, pipelines and transport systems, as well as …
What are the applications of Venturimeter?
A venturi meter is also called a venturi flowmeter. It is used to calculate the velocity of fluids in running through a pipeline. The fluid may be a liquid or a gas. The meter consists of a pipe with a narrowing throat that expands back to it’s original diameter on the other side of the choke point.
What are the main parts of Venturimeter?
A venturimeter consists of four parts:
- Cylindrical Inlet Section.
- Conical convergent Section.
- Cylindrical throat and.
- Conical divergent outlet.
What is the working principle of Venturimeter?
The principle of venturimeter is that when a fluid flows through the venturimeter, it accelerates in the convergent section and decelerates in the divergent section, resulting in a drop in the static pressure followed by a pressure recovery in the flow direction.
What are the advantages of Venturimeter over Orificemeter?
Advantages of venturi meter:
- Less chance of getting stuck with sediment.
- The discharge coefficient is high.
- Its behaviour can be predicted perfectly.
- It can be installed vertically, horizontally, inclined.
- They are more precise and can be used for a wide range of flows.
- About 90% of the pressure drop can be recovered.
Why Venturimeter is more accurate?
Higher flow rates in high quality orifice plates gives increased accuracy. Venturimeters are widely used for high flow rates. They can handle 25-50% more flow rate than an orifice.
Which is more accurate Venturimeter or orifice meter?
Most recent answer Measurement of mass flow rate of fluid in fluid mechanics is by meters (venturimeter, orifice meter) connected at the entrance and at throat by recording pressure drop by manometer. Out of these, venturimeter is found to be the most accurate device for measurement of mass flow rate.
